steam at 5 pma and 650 c enters adiabatic turbine at a velocity of 80 m/s. Following its expansion in the turvine, it exits at 50kpa 150c and a velocity of 140 m/s. thje power output of the turbine is 8 MW calculate the mass flow rate of the steam determine the state of the working fluid at the outlet of the turbine of the expansion was isentropic

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
