Apump delivers gasoline at 20°c and 14 m3/h. at the inlet, p1 = 100 kpa, z1 = 1 m, and v1 = 2 m/s. at the exit p2 = 500 kpa, z2 = 4 m, and v2 = 3 m/s. how much power is required if the motor efficiency is 75%? round the final answer to the nearest whole number. for gasoline, take rhog ≈ 680(9.81) = 6671 n/m3.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Atmospheric air has a temperature (dry bulb) of 80° f and a wet bulb temperature of 60° f when the barometric pressure is 14.696 psia. determine the specific humidity, grains/lb dry air. a. 11.4 c. 55.8 d. 22.5 b. 44.1
