Two kilograms of air within a piston-cylinder assembly executes a Carnot power cycle with maximum and minimum temperatures of 750K and 300K, respectively. The heat transfer to the air during the isothermal expansion is 60 kJ. At the end of the isothermalexpansion, the pressure is 600 kPa and the volume is 0.4 m3. Assuming the ideal gas model for air, determine the thermal efficiency.
System of force and cable tensions is in equilibrium and what are the necessary conditions for static equilibrium and determine the area moment of inertia about Ox for the area shown under the curve
Determine the reactions of simply supported beam to both a concentrated and uniform load. A beam with a span of 21 ft is simply supported at the left-hand end and fixed at the right-hand end.
Solve the problem in the image. Do it step wise in detail. This question is from book "Fracture Mechanics - An Introduction - E. Gdoutos Springer (Page 74)"
why is the correct tightening of friction grip bolts important?
In the an ideal turbo jet, the engine is designed such that the turbine work is divided equally between the compressor and the propeller. The gas from the turbine discharges to a nozzle for additional thrust.
Determine if the shaft has infinite fatigue life. If not, determine the number of cycles to failure. Also determine the safety factor for first cycle yield and draw a free body diagram, shear and moment diagrams, and graph the loads on the shaft..
Remember that velocity is a vector quantity so find the magnitude of the average velocity and the angle of average velocity from the horizon
Write a literature review and the title is "the effect of fluid cooling on the performance of building integrated photovoltaic thermal systems. Using some BIPVT prototypes measure their thermal and electrical output and dtermine their effectiveness"
The entrance is inward projecting. What flow will be expected if the gate valve is one-half open?
The mean diameter of a conical friction clutch is 250mm with a width of the conical surface being 50mm. The clutch is lined with a material having a coefficient of friction of 0.25
Effect of pressure on temperature and density of air for an adiabatic process, The pressure is to be raised from atmospheric to 7 psi (4.83 bar). The process is adiabatic, and the volume is constant and unknown.
A 0.4 W cylindrical electronic component with a diameter of 0.3 cm and length 1.8 cm is mounted horizontally on a circuit board. To cool the component air is flowing across the board at a velocity of 150 m/min. If the air temperature is T∞= 45°C, ..
