a piston-cylinder device contains 500L of saturated liquid refrigerant-134a. the piston is free to move, and its mass is such that it maintains a pressure of 800KPa on the refrigerant. the refrigerant is now heated at constant pressure until its temperature rises to 333k. calculate the work done during this process.
Aeroplane Dynamics, Determine the steady thrust that would enable a 200-tonne airliner to reach its take-off speed (75 m sâ?'1), from rest, in 30 s
The tank air pressure above the water level is 300kPa(absolute) while the atmospheric pressure is 100kPA. Neglecting frictional effects, determine the initial discharge rate of water from the tank.(Density of water=1000kg/m^3)
The temperature of the water drops to 260 F as a result of heat transfer to the surroundings. Determine the final pressure in the tank?
Prepare a 3-input, 5 bit multiplexer that fits in a 24-pin IC package. Write the truth table and draw a logic diagram and logic symbol for the multiplexer.

Sketch the T-s diagram for the cycle (put labels and appropriate information)
Calculate the value of forces P and Q for each test using the method of sections technique.
Twenty-five samples of steel beam were chosen and tested for Young's Modulus. Eight had a modulus of E = 30 x 10^6 psi. Two had a modulus of E = 29 x 10^6 psi. Fifteen had a modulus of E = 30. x 1-^6 psi.
A short 60-mm-diameter circular bar is made of a material for which the maximum safe compressive stress is 80 MPa and the maximum safe shearing stress is 30 MPa. Determine the maximum axial compressive force that can be safely applied.
