Enter the mass flow rate, specific heat, and temperature change into the calculator to determine the power output in kilowatts. This calculator helps in converting a mass flow rate from kg/h to power in kW.

## Kg/H to kW Formula

The following formula is used to convert a mass flow rate in kg/h to power in kW.

P (kW) = (ṁ / 3600) * c * ΔT

Variables:

• P is the power output (kW)
• ṁ is the mass flow rate (kg/h)
• c is the specific heat of the fluid (kJ/kg·K)
• ΔT is the temperature change (K)

To calculate the power output in kilowatts, convert the mass flow rate from kg/h to kg/s by dividing by 3600, then multiply by the specific heat and the temperature change.

## What is Specific Heat?

Specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius or Kelvin. It is a property that describes how much energy a substance can absorb before its temperature changes. The specific heat of a substance can vary depending on its state (solid, liquid, or gas) and temperature.

## How to Calculate Power Output from Mass Flow Rate?

The following steps outline how to calculate the power output from a mass flow rate in kg/h.

1. First, determine the mass flow rate (ṁ) in kg/h.
2. Next, determine the specific heat (c) of the fluid in kJ/kg·K.
3. Next, determine the temperature change (ΔT) in Kelvin.
4. Next, gather the formula from above = P (kW) = (ṁ / 3600) * c * ΔT.
5. Finally, calculate the power output (P) in kilowatts.
6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

Mass flow rate (ṁ) = 5000 kg/h

Specific heat (c) = 4.2 kJ/kg·K

Temperature change (ΔT) = 50 K
