6. a pump operating at steady state draws water from a pond and delivers it through a pipe whose exit is 90 ft above the inlet. at the exit, the mass flow rate is 10 lbm/s. there is no significant change in water temperature, pressure, or kinetic energy from the inlet to the exit. if the power required by the pump is 1.68 hp, determine the rate of heat transfer between the pump and its surrounds in hp and btu/min. (g = 32.0 ft/s^2.)
