The final result (the heat capacity) is calculated via. q tot = m tot c tot Δ T ⇒ c tot = q tot m tot Δ T = 2.868 k J 200 g × 3.38 K = 4.243 J g − 1 K − 1. This is a little bit more than the specific heat capacity of water, so we're good!

The overall heat transfer coefficient is a measure of the overall ability of a series of conductive and convective barriers to transfer heat. It is commonly applied to the calculation of heat transfer in heat exchangers, but can be applied equally well to other problems. For the case of a heat exchanger, can be used to determine the total heat transfer between the two streams in the heat exchanger by the following relationship:
