1. A two shell, eight tube pass STHE is to heat mineral oil from -5°C to 40°C using water with an inlet temperature of 80°C. The mass flow rates of the water and the oil are 10 kg.s¹ and 35 kg.s¹ respectively. The Overall Heat Transfer Coefficient of the heat exchanger is 285 W.m². If the diameter of the tubes is 30 mm, determine the total length of tube required in the heat exchanger.
