Enter the energy in Kj/Kg and the mass flow rate in Kg/s into the calculator to convert to power in kilowatts (kW).
Kj/Kg to kW Conversion Formula
The following formula is used to convert energy in Kj/Kg to power in kW.
P (kW) = (E (Kj/Kg) * ṁ (Kg/s)) / 1000
Variables:
- P is the power in kilowatts (kW)
- E is the energy in kilojoules per kilogram (Kj/Kg)
- ṁ is the mass flow rate in kilograms per second (Kg/s)
To convert energy in Kj/Kg to power in kW, multiply the energy value by the mass flow rate and then divide by 1000 to convert from Kj/s to kW.
What is Energy to Power Conversion?
Energy to power conversion is the process of converting a specific amount of energy per unit mass (Kj/Kg) to power (kW) using the mass flow rate. This conversion is particularly useful in engineering fields such as thermodynamics and mechanical engineering, where it is important to understand the power output of a system based on the energy content of the fuel or working fluid and the rate at which it is being consumed or processed.
How to Calculate Power from Energy and Mass Flow Rate?
The following steps outline how to calculate power from energy and mass flow rate.
- First, determine the energy content per unit mass (E) in Kj/Kg.
- Next, determine the mass flow rate (ṁ) in Kg/s.
- Use the formula P (kW) = (E (Kj/Kg) * ṁ (Kg/s)) / 1000 to calculate the power.
- Finally, enter the values into the calculator above to verify the result.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Energy content per unit mass (E) = 500 Kj/Kg
Mass flow rate (ṁ) = 2 Kg/s
