Liquid water at 100 psia and 300f (state 1) enters an adiabatic throttling valve steadily with a mass flow rate of 20 lbm/s and exits at a pressure of 45 psia (state 2). fluid leaving the valve enters a rigid, insulated flash chamber; saturated liquid at 45 psia (state 3) and saturated vapor at 45 psia (state 4) exit from the flash chamber. saturated vapor exiting the flash chamber expands through an adiabatic turbine to a pressure of 3 psia (state 5). the isentropic efficiency of the turbine is 90%. assume that the surrounding pressure is 1 atm and temperature is 55f.(a) calculate the power (btu/s) produced by the turbine. (b) determine rate of exergy destruction (btu/s) for throttling valve, flash chamber, and turbine. (c) show the entire process on t-s diagram. label states, show property values, and indicate appropriate lines of constant pressure.
