In a certain chemical plant, a closed tank contains ethyl alcohol to a depth of 71 ft. Air at a pressure of 17 psi fills the gap at the top of the tank. Determine the pressure at a closed valve attached to the tank 10 ft above its bottom.
Answer:
the pressure at a closed valve attached to the tank 10 ft above its bottom is 37.88 psi
Explanation:
Given that;
depth 1 = 71 ft
depth 2 = 10 ft
pressure p = 17 psi = 2448 lb/ft²
depth h = 71 ft - 10 ft = 61 ft
we know that;
p = P_air + yh
where y is the specific weight of ethyl alcohol ( 49.3 lb/ft³ )
so we substitute;
p = 2448 + ( 49.3 × 61 )
= 2448 + 3007.3
= 5455.3 lb/ft³
= 37.88 psi
Therefore, the pressure at a closed valve attached to the tank 10 ft above its bottom is 37.88 psi

Determining criteria and constraints is part of which steps in the engineering design phase? doing an analysis researching the problem brainstorming solutions defining the need
Answer:
defining the need
Explanation:
Of course, since the first stage of the engineering design phase involves defining the need of the design, it is at this stage that the researcher/engineer should determine the criteria and constraints.
This stage involves asking such questions as:
What restrictions or limitations exist that should be considered in the design?What design requirements do I need so the product can achieve the objective?CAN I GET ANSWERS PLEASE, I TRY THE FORMULA AND MY TEACHER HAS A FAMILY EMERGENCY SO HE CANT RESPOND BACK SO PLEASE HELP ME
Explanation:

You'll need to use Ohm's Law and Kirchhoff's Voltage Law.
Remember Ohm's Law as [tex]V = IR[/tex].
Kirchoff's Voltage Law says that the sum of voltages for a given circuit "loop" must equal zero. In the circuit shown, this means that the voltage provided by the battery (E_T) equals the voltage drop across each of the three resisters in the loop.
[tex]E_T = E_1 + E_2 + E_3[/tex]
A couple of other helpful notes:
These three resistors are in series which means that the current flowing through them is equal.
So it is easy to see that... [tex]V = IR \rightarrow E_1 = 4*2 = 8 V[/tex]
Solve for the voltage across E_2 and E_3. The sum of the three voltages equals the voltage of the battery (E_T).

A ten story hospital has to constructed with the footprint of 45,000 ft^2. Subsurface soil consist of soft clay layer of 10 ft. Deep pile foundation will be used for supporting the building. The depth of pile foundation will be the 15ft.
Required:
a. Determine number of the boring to be used for the subsurface investigation using NYC Code Mandate discussed in the class.
b. Also determine the depth of the boring to be used for subsurface investigation.
Answer:
a) approximately, the number of bores to be used is 17
b) depth of the boring is 25 ft from ground level
Explanation:
Given the data in the question;
we know that; The New York City Code mandate; deep foundation clause Number 1802.4.1 states that required number of borings shall not be less than two boring
i.e a minimum Number of 1 boring per 2000 square foot for the first 20,000 square foot and one boring per every additional 4000 square foot
so;
number of the boring to be used for the subsurface investigation using NYC Code Mandate will be;
⇒ 20,000/2000 + [( 45,000 - 2000)/4000]
= 10 + 6.25
= 16.25 ≈ 17
approximately, the number of boring to be used is 17
b)
the depth of the boring to be used for subsurface investigation will be;
⇒ 10 ft + 15 ft
= 25 ft
Therefore, depth of the boring is 25 ft from ground level

Explanation:
University administrators have developed a Markov model to simulate graduation rates at their school. Students might drop out, repeat a year, or move on to the next year. Students have a 3% chance of repeating the year. First-years and sophomores have a 6% chance of dropping out. For juniors and seniors, the drop-out rate is 4%. Compute the probability that a student who starts as a 1st-year eventually graduates the university.
Solution :
The percentage of the students who have a chance of repeating their current year = 3%
The drop out students for the first year and the sophomores = 6%
Drop out rate of first year and the seniors = 4%
Now for the state space :
S = { first year(1), sophomores(2), juniors(3), seniors(4), graduates(G), Dropouts(D) }
Therefore
the first year students are indicated as '1'
Sophomores are indicated as '2'
Juniors are indicated as '3'
Seniors are indicated as '4
Graduates are indicated as 'G'
Dropouts are indicated as 'D'
The transition diagram is attached below.
The probability of the students who have the chance of repeating their current year = 3/100 = 0.03
Probability of first year dropouts and sophomores = 6/100 = 0.06
Probability of dropout rate of juniors and seniors = 4/100 = 0.04
Therefore, the probability matrix can be made as :

Acertain foundation will experience a bearing capacity failure when it is subjected to a downward load of 2200 kN. Using ASD with a factor of safety of 3, determine the maximum allowable loadthat will satisfy geotechnical ULS requirements.
Answer:
550kN
Explanation:
We are required to find the maximum allowable load that will satisfy geotechnical ULS requirements
P' = pu/FOS ---1
Pu = design load
FOS = factor of safety
We get the design of safety
Pu = 0.75p
= 0.75 x 2200
= 1650kN
Factor of safety = 3
Design load = 1650
P' = 1650/3
= 550kN
So we have the maximum allowable load to be 550kN
The characteristics of water flow over a dam spillway are to be measured in a geometrically similar small-scale laboratory model. The width of the prototype is 30 m and the width of the model is 2 m. If the flow in the prototype is 100 m3/s, the flow rate in the model for similitude is:
Answer:
[tex]Q_m \simeq 0.11 \ m^3/sec[/tex]
Explanation:
From the given information:
The width of the prototype [tex]L_p[/tex] = 30 m
The flow of the prototype [tex]Q_p[/tex] = 100 m/s
width of the model [tex]L_m[/tex] = 2 m
The flow rate of the model can be calculated by using the geometrical similarities of Froude's Number Fr
[tex](Fr)_m = (Fr)_p[/tex]
[tex]\implies ( \dfrac{v}{\sqrt{ gy} }) _m = ( \dfrac{v}{\sqrt{gy}}) _p[/tex]
[tex]V_r = \sqrt{L_r}--- (1)[/tex]
[tex]Q_r = V_r *A_r[/tex]
[tex]Q_r = \sqrt { L_r} *L_r^2[/tex]
[tex]Q_r = L_r^{2.5}[/tex]
∴
[tex](\dfrac{Q_m}{Q_p}) = (\dfrac{L_m}{L_p})^{2.5}[/tex]
[tex](\dfrac{Q_m}{100}) = (\dfrac{2}{30})^{2.5}[/tex]
[tex](\dfrac{Q_m}{100}) =0.001147550621[/tex]

g Asbestos is a fibrous silicate mineral with remarkably high tensile strength. But is no longer used because airborne asbestos particles can cause lung cancer. Grunerite, a type of asbestos, has a tensile strength of 3.5 × 10ଶ kg mmଶ ⁄ (meaning a strand of grunerite with a 1-mmଶ cross-sectional area can hold up to 3.5 × 10ଶ kg). The tensile strength of aluminum and Steel No. 5137 are 2.4 × 10ସ lb inଶ ⁄ and 5.0 × 10ସ lb inଶ ⁄ respectively. Calculate the cross section areas in mmଶ of wires of aluminum and of Steel No. 5137 that have the same tensile strength as a fiber of grunerite with a cross-sectional area of 1.0 μmଶ
Answer:
Aluminum cross sectional area = 1.99 * 10^-5 mm^2
Steel cross sectional area = 9.95* 10^-6 mm^2
Explanation:
Given data:
Tensile strength of Grunerite = 3.5 * 10^2 kg/mm^2 = 3.5 * 10^-4 kg/um^2
Tensile strength of Aluminum = 2.5 × 10^4 lb/in2 = 2.5 × 10^4 * 703.07 kg/m^2
Tensile strength of Steel number 5137 = 5.0 × 10^4 lb/in2 = 5.0 × 10^4*703.07 kg/m^2
Calculating the cross sectional area of the wires of aluminum and steel No5137
first we will determine the cross sectional area of the aluminum wire ( A ) by equating tensile strength of aluminum with the tensile strength
of Grunerite
(2.5 × 10^4 * 703.07) * A = 3.5 * 10^-4 kg
Hence ; A = 1.99 * 10^-5 mm^2
Next we calculate the cross sectional area of steel
5.0 × 10^4*703.07 kg/m^2 * A" = 3.5 * 10^-4 kg
Hence ; A" = 9.95* 10^-6 mm^2

A compressor receives air at 290 K, 95 kPa and shaft work of 5.5 kW from a gasoline engine. It should deliver a mass flow rate of 0.01 kg/s air to a pipeline. Find the maximum possible exit pressure of the compressor.
Answer:
P2 = 3.9 MPa
Explanation:
Given that
T₁ = 290 K
P₁ = 95 KPa
Power P = 5.5 KW
mass flow rate = 0.01 kg/s
solution
with the help of table A5
here air specific heat and adiabatic exponent is
Cp = 1.004 kJ/kg K
and k = 1.4
so
work rate will be
W = m × Cp × (T2 - T1) ..........................1
here T2 = W ÷ ( m × Cp) + T1
so T2 = 5.5 ÷ ( 0.001 × 1.004 ) + 290
T2 = 838 k
so final pressure will be here
P2 = P1 × [tex](\frac{T2}{T1})^\frac{k}{k-1}[/tex] ..............2
P2 = 95 × [tex](\frac{838}{290})^\frac{1.4}{1.4-1}[/tex]
P2 = 3.9 MPa

A force of 12 N is applied to a block moving west. Another force of 26 N is being applied in the opposite direction. The block weighs 7kg. What is the net force and the acceleration?
Answer:
[tex]F_{Net} = 14N[/tex]
[tex]a = 2m/s^2[/tex]
Explanation:
Given
[tex]Mass = 7kg[/tex]
[tex]F_{west} = 12N[/tex]
[tex]F_{opposite} = 26N[/tex]
Solving (a): The net force:
The force towards the west direction, will be regarded as negative while the opposite force will be regarded as positive.
So, the net force is:
[tex]F_{Net} = -F_{west} + F_{opposite}[/tex]
Substitute values for the given forces
[tex]F_{Net} = -12N + 26N[/tex]
[tex]F_{Net} = 14N[/tex]
The net force is 14 N
Solving (b): Acceleration
Net force is calculated as:
[tex]F_{Net} = Mass * Acceleration[/tex]
Substitute 7 kg for Mass and 14 N for Net force:
[tex]14N = 7kg* a[/tex]
Make a the subject:
[tex]a = \frac{14N}{7kg}[/tex]
[tex]a = 2N/kg[/tex]
[tex]a = 2m/s^2[/tex]
Hence, the acceleration is [tex]2m/s^2[/tex]

A sample of blue gray soilwas obtained from Paine Field in Everett, WA to determine its Atterberg Limits and classify itssoil type according to the Unified Soil Classification system.84% of the sample passed through the #200 sieve with 16% retained on the #4 sieve. For one of the PL determinations, the wet weight + dish = 11.53 grams and the dry weight + dish = 10.49 grams. The dish only weighed 4.15 grams. Compute the plastic limit. Three determinations of the liquid limit were made. For 17 blows, the water content was 49.8%; for 26 blows, the water content was 47.5%; and for 36 blows, the water content was 46.3%.
Required:
Evaluate the soil type, indicate the information on a plasticity chart,and give the Unified Soil Classification System (USCS) symboland the proper narrative description.
Solution :
1. PL [tex]$= \frac{11.53 - 10.49}{10.49 - 4.5} \times 100$[/tex]
= 17.36 %
2. Liquid limit at 25 number of blows,
[tex]$LL = \frac{(26-25)\times 49.8 + (25 - 2.17) \times 47.5}{26-17}$[/tex]
[tex]$= 47.75 $[/tex] %
Since 84 % of the passes the number 200 sieve the soil is immediately fine grained and MI, OI or CI because LL = 47.75 % > 35%
Therefore, the Plasticity index, PI [tex]$=47.75 - 17.36 = 30.39$[/tex] %
Equation of A-line [tex]$= 0.73 \times [47.75 - 20]$[/tex]
[tex]$=20.25 $[/tex] %
Thus the soil lies above the A-line, that is soil is medium compressible clay ---- CI

The pressure at a point in a pipeline is 80 kPa. Assuming standard atmospheric pressure, the absolute pressure in the pipeline is most nearly:
Answer:
[tex]P_{a}=181.324 kPa[/tex]
Explanation:
The pressure you measure on a pipeline is generally a gauge pressure, this is the difference between the pressure inside the pipe and the atmospheric pressure.
In order to find the absolute pressure, we need to add the pressure in the atmosphere to the measured pressure, so we get:
[tex]P_{a}=80kPa+101.325kPa[/tex]
the 101.325kPa is the equivalent to 1atm, so we get:
[tex]P_{a}=181.325kPa[/tex]
