79: An oil with a flow rate of 1000 kg/h is to be cooled using water in a double pipe counter- flow heat exchanger from a temperature of 70°C to 40°C. Water enters the exchanger at 25°C and leaves at 40°C. The specific heats of oil and water are 2kJ kg ¹ K¹ and 4.2 kJ kg- K¹, respectively. The overall heat transfer coefficient is 0.2 kW m2 K¹. The minimum heat exchanger area (in m² required for this operation,is)
