Question

• Water at 93.5 °C is pumped from a storage tank at
the rate of 3.15x10-3 m3/s. The motor for the pump
supplies work at the rate of 1.5 kW. The water goes
through a heat exchanger, giving up heat at the rate
of 700 kW, and is delivered to a second storage tank
at an elevation 15 m above the first tank. What is the
temperature of the water delivered to the second
tank? The density of water at 93.5 °C is 958 kg/m3​
