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)

To calculate water cooling energy, multiply the water mass flow rate by the change in temperature caused by the water, then again by the specific heat of the water.

## 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)
