"A mass-loaded piston-cylinder system containing air is at 40 lbf/in^2" , 500 °R with a volume of 11 ft3 , while at the stops V = 38 ft3 . An air supply line at 1040 °R is connected to the system by a valve. The valve is then opened until a final pressure of 55 lbf/in.2 at T = 620 °R is reached inside the piston-cylinder assembly. Determine (a) the air mass that enters, (b) the work done in Btu, and (c) the heat transfer in Btu. (Hint: The air is modeled as an ideal gas and the pressure is constant until it reaches to the final pressure).

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
