Water is pumped from a lower reservoir to a higher reservoir by a pump that provides 20 kw of shaft power. the free surface of the upper reservoir is 45 m higher than that of the lower reservoir. if the flow rate of water is measured to be 0.03 m3/s, determine mechanical power that is converted to thermal energy during this process due to frictional effects
