Aliquid reactant (rho = 72 lbm/ft3 , μ = 0.0040 lbm/ft s) is pumped from a holding tank at atmospheric pressure through 2300 ft of 6" id steel pipe and into a reactor at an absolute pressure of 5.0 atm. the reactor is at a level 100 ft below the holding tank. the mass flow rate is 90,000 lbm/hr. • find the power (in hp) required for a 50% efficient pump.

On a average work day more than work place firs are reorted

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.
