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]
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.

If the wedge has an angle of 5° determine the minimum value of the force P2, parallel to the fixed surface on the left, required to begin moving the block up the incline.
Assuming the wedge has an angle of 5°.The minimum value of the force P that is required to begin moving the block up the incline is: 322.84 N.
Minimum value of force PFirst step
Using this formula to find the weight of the block
W=mg
W=27×9.81
W=264.87 N
Second step
Angles of friction ∅A and ∅B
∅A=tan^-1(μA)
∅A=tan^-1(0.70)
∅A=34.99°
∅B=tan^-1(μB)
∅B=tan^-1(0.40)
∅B=21.80°
Third step
Equate the sum of forces in m-direction to 0 in order to find the reaction force at B.
∑fm=0
W sin (∅A+20°) + RB cos (∅B+∅A)=0
264.87 sin(34.99°+20°) + RB cos (21.80°+34.99°)=0
216.94+0.5477Rb=0
RB=216.94/0.5477
RB=396.09 N
Fourth step
Equate the sum of forces in x-direction to 0 in order to find force Rc.
∑fx=0
RB cos (∅B) - RC cos (∅B+ 5°)=0
396.09 cos(21.80°) - RC cos (21.80°+5°)=0

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

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.

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
