## 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**

- 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 .
- 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 .
- Next, determine the change in temperature (C). In this case, the change in temperature (C) is found to be 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)
