A pump is used to move water from a lower reservoir to a higher reservoir with an elevation difference of 45 m with respect to the lower reservoir. The water has a volume flow measured at 0.03 m³/s. If the pump provides 20 kW of shaft power, calculate the mechanical power that is converted to thermal energy due to frictional effects. Show allof your work in symbolic form, and then provide the calculations. Report your answer in1-W.
