Write the energy and mass equations if the control
volume is set to be the whole figure.
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: Write the energy and mass equations if the control volume is set to be the whole figure. Saturated vapor, P2 = 4 bar 2 Valve 1 Turbine P = 15 bar T = 180°C m = 5 kg/s 3 Saturated liquid, -Flash chamber P3 = 4 bar P4 = 0.08 bar X4 = 90%
