(For numbers 4 to 10) A double-pipe heat exchanger (counterflow operation) having an area of 100 m² is used to heat 5 kg/s of water that enters<br>the heat exchanger at 50 °C. The heating fluid is oil having a specific heat of 2.1 kJ/kg-°C and a flow rate of 8 kg/s. The oil enters the exchanger<br>at 100 °C and the overall heat-transfer coefficient is 120 W/m2.°C.<br>
