Water enters a 13-cm-diameter pipe steadily with a uniform velocity of 2 m/s and exits with the turbulent flow velocity distribution given by u = umax(1 − rR)1/7 . If the pressure drop along the pipe is 10 kPa, determine the viscous force exerted in the pipe by the water flow. Take the density of water to be 1000 kg/m3. The average velocity is equal to 0.816 times the max velocity. The viscous force exerted in the pipe by the water flow is 50

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.
