Find the heat transfer to the water and the work input

Reference no: EM131233100

1. A closed tank, V = 0.35 ft³, containing 10 lbm water initially at 77 F, is heated to 350 F by a heat pump that is receiving heat from the surroundings at 77 F. Assume that this process is reversible. Find the heat transfer to the water and the work input to the heat pump.

2. A cylinder containing R-134a at 60 F, 30 lbf/in.² has an initial volume of 1 ft3. A piston compresses the R-134a in a reversible isothermal process until it reaches the saturated vapor state. Calculate the work and heat transfer required to accomplish this process.
