explain the S.A. co-ordinate system used in surveying
Answer:
A coordinate system is a method for identifying the location of a point on the earth. Most coordinate systems use two numbers, a coordinate, to identify the location of a point. Each of these numbers indicates the distance between the point and some fixed reference point, called the origin

Answer:
4.2
Explanation:
The "allowance" is the difference between the maximum shaft size and the minimum hole size.
maximum shaft = C +D = 8.5 +0.1 = 8.6
minimum hole = A -B = 4.8 -0.4 = 4.4
Allowance = 8.6 -4.4 = 4.2
__
For an interference fit, the allowance is negative.

Where's an inductor most likely to be found in a power-supply circuit?
Which of these items is least likely to cause an exhaust emission test failure as of a result of excessive nox emissions? a) poorflow through the egr system. b) spark plug hot range. c) defective fuel injector d) defective oxygen senor
The item that is least likely to cause an exhaust emission test failure as of a result of excessive nox emissions is; poorflow through the egr system.
What is an exhaust emission?Exhaust emissions simply means substances emitted into the atmosphere from the exhaust discharge nozzle of an aircraft or aircraft engine.
Now, when the test fails as a result of excessive nox emissions, we can say that high NOx emissions can occur when an engine's air-fuel mixture is too lean. Thus, we can conclude that the reason for exhaust emission test failure as of a result of excessive nox emissions is due to poorflow through the egr system.

what is the temperature difference maintained between the air temperature and the wire in a hot wire sensor?
Answer:
A temperature sensor is installed upstream of the hot wire. The hot wire is then heated to a temperature higher than the air temperature determined by the temperature sensor. As the hot wire is cooled by the incoming air, the heating current must be increased to maintain a constant wire temperature.

An amount P is deposited now so that an equal annual amount of A1=2000 per year for the first 5 years, starting 1year after the deposit. And a different annual withdrawal of A2= 3000 per year for the following 3 years. Draw the cash flow diagram if i=8.5% per year.
Based on the amounts to be withdrawn over the years and the interest rate, the amount deposited now is $12,977.
How much is deposited now?This can be found as:
= (2,000 x Present value of annuity interest factor, 8.5%, 5 years) + (3,000 x Present value of annuity interest factor, 8.5%, 8 years) - (P/A, 8.5%, 5 years)
= (2,000 x 3.9406) + (3,000 x (5.6392 - 3.94064))
= $12,977

A 750-m section of river runs parallel to a channel 1,000 m away. an aquifer connecting the two has hydraulic conductivity equal to 7. 0 m/day and an average thickness of 10 m. the surface of the river is 5. 0 m higher than the surface of the channel. estimate the rate of seepage (qseepage) from the river to the channel
Given a 750 m section with distance of 1000m , The calculated rate of seepage from the river to the channel has been calculated to be 262.5 m³/day.
What is the rate of seepage?
This is the calculated rate that shows how water is infiltrated downward into the soil.
The formula is given as
[tex]Q = KA \frac{dh}{dl}[/tex]
A = Area = 750*10 = 7500m
dh = h₂-h₁
= 10 - 5 = 5m
dl = 1000m
[tex]Q = 7*7500*\frac{5}{1000}[/tex]
= 262.5m³
The rate of seepage from the calculation above is 262.5m³.

A closed thermodynamic cycle consists of two isobaric and two isochoric processes. The processes operate between 0.43 MPa and 4.3 MPa and 0.28 m3 and 2.9 m3. Determine the total work (with appropriate sign) for one complete cycle, when the cycle operates in the clockwise direction. Provide your result in MJ.
Answer:
Explanation:
For first isobaric process (expansion with constant pressure):
[tex]W_{1}=P_{1}(V_{2}-V_{1})=(0.43\times 10^{6})(2.9-0.28)=1.1266 \times 10^{6} J=1.1266 MJ(+) (Expansion)[/tex]
Now, for the first isochoric: [tex]W_{2}=0[/tex], and [tex]Q_{2}=\Delta U=U_{3}-U_{2}[/tex]
For the second isobaric process (compression with constant pressure):
[tex]W_{3}=P_{2}(V_{1}-V_{2})=(4.3\times 10^{6})(0.28-2.9) =-11.266\times 10^{6}J=-11.266 MJ (Compression)[/tex]
For the last isochoric: [tex]W_{4}=0, Q_{4}=\Delta U=U_{4}-U_{3}[/tex]
So, the total work per cycle: [tex]W=W_{1}+W_{2}+W_{3}+W_{4}=1.1266+0-11.266+0=-10.1394 MJ[/tex]

A gaseous mixture contain 32.9 mol % He, 40.7 mol % N_{2} and 26.4 mol % Ar. Determine the composition of this mixture on a mass basis based on the molecular weight given: MW(He) = 4.003 , MW (N_{2}) = 28.02 MW(Ar) = 39.95
The composition of the mixture on a mass basis are as follows:
He = 131.70 gN2 = 1140.41 gAr = 1054.68 gnumber of moles = mass of substnce / molar mass
molar mass and molecular weight has equal numerical values therefore
Number of moles = mass of substnce / molecular weight
mass of substance = number of moles * molecular weight
the moles are expressed in percentage hence the total moles should be 100
check: 32.9 + 40.7 + 26.4 = 100
He
mass of substance = 32.9 * 4.003 = 131.6987 g
[tex]N_{2}[/tex]
mass of substance = 40.7 * 28.02 = 1140.414 g
Ar
mass of substance = 26.4 * 39.95 = 1054.68 g
An evacuated tank is filled with gas from a constant pressure line. Develop an expression relating the temperature of the gas in the tank to the temperature of the gas in the line. Assume the gas is ideal with constant heat capacities, and ignore heat transfer between the gas and the tank.
The temperature of the gas in the tank is the ratio of heat capacities times the temperature of gas in the constant pressure line.
What is temperature?It should be noted that temperature simply means the measure of hotness and coldness in a body
From the given information, H is the enthalpy of gas on the constant pressure line, m is the mass flow rate and U is the internal energy of gas.
Here, the temperature of the gas in the tank is the ratio of heat capacities times the temperature of gas in the constant pressure line.

Joe is a chemical engineer whose plant discharges heavy metals into the local river. By the test authorized by the city government, the amount of heavy metals is under the legal limit imposed by the city. By a new and more accurate test, the discharge is above the legal limit, that is, the discharge is in violation of environmental rules. Joe argues with his manager that the plant should reduce its discharges to comply with the newer and more accurate test.
The case contains a conceptual issue insofar as:
A.the issue is whether present emission rates constitute a violation of city regulations.
B.the issue is what is meant by “violation.”
C.the issue is how Joe should balance his obligations to his employer against his obligations to city residents.
D.the issue is whether the heavy metals presently emitted by the plant pose a threat to the health of the community.
Answer:
B probably
Explanation:
Because the prompt doesn't specify what sort of violation it could be anything maybe when they release the metals during the day and so on.
A farmer has 12 hectares of land on which he grows corn, wheat, and soybeans. It costs $4500 per hectare to grow corn, $6000 to grow wheat, and $5000 to grow soybeans. Because of market demand the farmer will grow twice as many hectares of wheat as corn. He has allocated $6,375,000.00 for the cost of growing his crops. How many hectares of each crop should he plant?
The number of hectares of each crop he should plant are; 250 hectares of Corn, 500 hectares of Wheat and 450 hectares of soybeans
How to solve algebra word problem?
He grows corn, wheat and soya beans on the farm of 1200 hectares. Thus;
C + W + S = 12 ----(1)
It costs $45 per hectare to grow corn, $60 to grow wheat, and $50 to grow soybeans. Thus;
45C + 60W + 50S = 63750 -----(2)
He will grow twice as many hectares of wheat as corn. Thus;
W = 2C ------(3)
Put 2C for W in eq 1 and eq 2 to get;
C + 2C + S = 1200
3C + S = 1200 -----(4)
45C + 60(2C) + 50S = 63750
45C + 120C + 50S = 63750
165C + 50S = 63750 ------(5)
Solving eq 4 and 5 simultaneosly gives;
C = 250 and W = 500
Thus; S = 1200 - 3(250)
S = 450
