The answer is 361 W/m2-C.

This approach is most commonly used when the building manager or engineer is trying to determine the heat transfer coefficient and outflow fluid temperature and already knows the heat exchanger size and inflow temperature. Subtract the end temperature from the start temperature to get the difference.

You can calculate the efficiency of anything by dividing the energy input and energy output by 100%. We usually use this equation to express energy as heat or electricity. For relatively low-pressure equipment, if the design pressure on the low side is more than two-thirds of the design pressure on the high side a full pipe rupture is not a realistic scenario.
