Apipe of diameter 200 mm (constant) carrying water with an 5 mis and total head is density 1000 kg/m ) with velocity tpward slope. at a certain point, where the elevation is 5 m above a datum, the 21.5 m. a) determine the pressure of the pipe at 5m elevation. determine the pressure at elevation 10m (above same datum) if the of total head at 5m elevation.

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.
