A piston heat engine takes 0.450 moles of ideal monatomic gas around a cycle described as follows: T1= 300 K, T2= 600 K, and T3= 492 K Process A: 1 To 2 Isochoric. Process B 2 To 3 Adiabatic. Process C 3 To 1 Isobaric at a pressure of 2.00 atm. A. Find the pressure and the volume at points 1, 2, and 3. B. Calculate Q, W, and AU for each of the three Find the network done by these processes. C. Find the net work done by the gas in the cycle.

Liquid water at 35 ºF is fed to a boiler operating at 10 bars and is converted at constant pressureto saturated steam. The steam is produced at a steady state flow rate of 600 lbm/hr. Assume thatthe kinetic energy of the liquid entering the boiler is negligible, and that the steam is dischargedfrom the boiler through a 1 ft pipe.a. Calculate ∆Ĥ (in units of Btu/lbm) for this process.b. Calculate the heat input (Btu/hr) to meet the needed saturated steam production rate.

A reheater cycle with two stages of reheating is executed with steam expanding initially from 20.111 Mpa and 540oC. The pressures of two heaters are 3.2111 Mpa and 0.85111 Mp, and the steam leaves each reheater at 540oC. Condensation occurs at 70oC. Calculate W, ec and ee.
