10-Q4 An ideal regenerative steam power cycle operates with steam that enters the turbine at 30 bars and 5000C and leaves the condenser as a saturated liquid at 0.1 bar. A single closed feed water heater is used with steam entering at 5 bars. Determine (a) the thermal efficiency of the cycle, (b) the mass flow rate through the cycle, in kg/hr and (c) the mass flow rate through the condenser, in kg/hr for the net power output of 100 MW.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
