Heat Exchanger Problem

10-64 A counterflow double-pipe heat exchanger is used to heat water from 20 °C to 40 °C with a hot oil that enters the exchanger at 180 °C and leaves at 140 °C. The flow rate of water is 3.0 kg/s and the overall heat-transfer coefficient is 130 W/m2 · °C. Assume the specific heat for oil is 2100 J/kg · °C. Suppose the water-flow rate is cut in half. What new oil flow rate would be necessary to maintain a 40 °C outlet water temperature? (The oil flow is not cut in half.)
