Apump transfers water from the upper reservoir to the lower one as shown in fig. p5.63a. the difference in elevation between the two reservoirs is 100 ft. the friction head loss in the pumping is given by kl*v^2/2g, where v is the average fluid velocity in the pipe and kl is the loss coeffiecient, which is considered constant. the relation between the head added to the water by the pump and the flowrate, q, through the pump is given in fig p5.63b. if kl=20, and the pipe diameter is 4 in., what is the flowrate through the pump?

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.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
