The pistоn/cylinder setup shоwn belоw contаins 0.5 kg of аmmoniа at −20∘C with a quality of 25%. The ammonia is now heated to +20∘C, at which state the volume is observed to be 1.41 times the initial volume. State 1: T1= -20 ∘C, P1 = 190.2 kPa, v1=0.15696 m3/kg, u1=391.44 kJ/kg State 2: T2= 20 ∘C, P2= 600 kPa, v2=0.2213 m3/kg, u2=1347.9 kJ/kg A. Find the work the ammonia produced. (5 pts)B. Find the heat transfer. (5 pts) Please (1) do the calculations on paper, and (2) provide numerical answers here.
