A tank at an elevation of z1 = 15 m contains 0.005 kg of saturated liquid H2O at T1 = 200 C and is attached to a paddle wheel. Take the reference state to be T0 = 25 ?C and p0 = 101.3 kPa. Compute the exergy transfer due to the process and the amount of exergy destroyed in kJ, if the only occurring process is:
Question:
a) 10 kJ of work performed by the paddle that brings the H2O to x = 0.8.
b) 10 kJ of heat gained from the surroundings at an average surface temperature of Ts = 250 C.
c) 10 kJ of potential energy is gained due to change in height.
