Enter the mass flow rate of the water (kg/s), the specific heat of the water (kJ/kg-K), and the change in temperature (C) into the calculator to determine the Water Cooling Energy. 

Water Cooling Energy Formula

The following equation is used to calculate the Water Cooling Energy.

Q = mdot * C * T

  • Where Q is the Water Cooling Energy (kW)
  • mdot is the mass flow rate of the water (kg/s) 
  • C is the specific heat of the water (kJ/kg-K) 
  • T is the change in temperature (C) 

How to Calculate Water Cooling Energy?

The following example problems outline the steps and information needed to calculate the Water Cooling Energy.

Example Problem #1

  1. First, determine the mass flow rate of the water (kg/s). In this example, the mass flow rate of the water (kg/s) is determined to be 5 .
  2. Next, determine the specific heat of the water (kJ/kg-K). For this problem, the specific heat of the water (kJ/kg-K) is measured to be 4.19 .
  3. Next, determine the change in temperature (C). In this case, the change in temperature (C) is found to be 4.
  4. Finally, calculate the Water Cooling Energy using the formula above: 

Q = mdot * C * T

Inserting the values from above and solving the equation yields: 

Q = 5 * 4.19 * 4 = 83.8 (kW)


Example Problem #2

Using the same method as above, first, we need to measure or determine the variables required by the equation. For this example problem, these are provided as follows: 

mass flow rate of the water (kg/s) = 9

specific heat of the water (kJ/kg-K) = 4.19

change in temperature (C) = 5

Enter these given values into the calculator or above yields: 

Q = 9 * 4.19 * 5 = 188.55 (kW)
