119:11 A turbine is to be used in a steam power plant (see the figure) that operates on a Rankine cycle. The boiler feeds steam into the turbine with a temperature of 420 °C and pressure of 30 bar. The mass fraction of liquid water in the exit of the turbine must not exceed 11%. boiler turbine Wochen w pumo pump condenser a. Determine the maximum work the turbine generates per kg of water passing through if we assume isentropic expansion in the turbine. Also determine the pressure in the exit of the turbine under the maximum work condition. IQcI Steam from the boiler with the same properties as above is now fed into a different turbine that has a thermodynamic efficiency of 85%. The exit pressure of this turbine is fixed at Pout = 0.50 bar. b. Determine the work this turbine generates per kg of water passing through and determine the mass fraction of liquid water at its exit.
