In a TEMA – E type shell-and-tube exchanger, as shown in the schematic diagram, water enters the shell at 218 °C at a rate of 1.4 kg/s. Engine oil flows through the tubes at a rate of 1.0 kg/s. The inlet and outlet temperatures of the oil are 150 °C and 90 °C, respectively. Determine the surface area of the exchanger by both the LMTD and E-NTU methods if U = 225W / (m ^ 2) * K The specific heats of water and oil are 4.19 and 1.67 J/g K respectively.
