Question

How to calculate entropy change during heat exchangers?

Answer 1

There is a simple equation for the entropy change of the surroundings. ΔH is the enthalpy change for the reaction. T is the temperature. ... But entropy changeis quoted in energy units of J. That means that if you are calculating entropy change, you must multiply the enthalpy change value by 1000.

Answer 2

Entropy Change in Heat Exchange of Liquids ... specific heat of 0.6 kcal/kg.oC. The water enters at 20oC. Determine.
