Unformatted text preview: conditions? (3 points) 2. Hot oil at 120ºC with a flow rate of 95 kg/min is used in a shellandtube heat exchanger with one shell pass and two tube passes to heat 55 kg/min of water which enters at 30ºC. The surface area of the exchanger is 14 m 2 . Calculate the heat transfer rate and exit temperatures of both fluids if the overall heat transfer coefficient is 250 W/m 2 K. The heat capacity of the oil is 1920 J/kg K. (3 points)...
