Calculation Formula

P (kW) = (ṁ (kg/h) × 1000) / (3600 × ρ (kg/m³) × c_p (J/kg·K) × ΔT (°C))

Where:
P = Power (kW)
ṁ = Mass Flow Rate (kg/h)
ρ = Density (kg/m³)
c_p = Specific Heat Capacity (J/kg·K)
ΔT = Temperature Difference (°C)

Result

0.00 kW

How to Use This Calculator

  1. Enter the Mass Flow Rate in kilograms per hour (kg/h).
  2. Enter the Density of the substance in kilograms per cubic meter (kg/m³). Default is set to 1000 for water.
  3. Enter the Specific Heat Capacity of the substance in joules per kilogram per kelvin (J/kg·K). Default is set to 4186 for water.
  4. Enter the Temperature Difference in degrees Celsius (°C).
  5. Click the Calculate button to get the power in kilowatts (kW).
  6. Click the Reset button to clear all input fields and results.

Principle Explanation

This calculator converts a flow rate of mass (kg/h) into power (kW) based on the specific heat capacity and temperature difference. The formula used is derived from the energy balance principle:

P = Q / t = (m × c_p × ΔT) / t

Where:

  • P = Power (kW)
  • Q = Heat Transfer (kJ)
  • t = Time (s)
  • m = Mass (kg)
  • c_p = Specific Heat Capacity (J/kg·K)
  • ΔT = Temperature Difference (°C)

The calculator adjusts the flow rate from kg/h to kg/s by dividing by 3600 and then applies the formula to find the power in kilowatts.
