Water from a reservoir flows through the 150-m long, 50-mm diameter pipe into the turbine at B. If the head loss in the pipe is 1.5 m for every 100-m length of pipe, and the water exits the pipe at C with an average velocity of 8 m/s, determine the power output of the turbine. The turbine operates at 60% efficiency. How many homes can this turbine provide electricity to? (You will need to find the typical energy usage for a home – cite your source.)

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.
