Answer questions (a) and (b):
Hot industrial wastewater at 15 bar, 180 degrees Celsius with a mass flow rate of 5 kg/s enters a flash chamber via a valve. Saturated vapor and saturated liquid steams, each at 4 bar, exit the flash chamber. The saturated vapor enters the turbine and expands to 0.08 bar, x = 90%. Stray heat transfer and kinetic and potential energy effects are negligible. For operation at steady state: (a) determine the power developed by the turbine, (b) write the energy and mass equations if the control volume is set to be the whole figure. Saturated vapor, P2 = 4 bar 2. Valve Turbine P = 15 bar T = 180°C m = 5 kg/s 3 -Flash chamber Saturated liquid, P3 = 4 bar P4 = 0.08 bar *4 = 90%
