How to Use This Calculator
- Enter the Mass Flow Rate in kg/hr of the process stream.
- Enter the Specific Heat (Cp) in kJ/(kg·°C): water = 4.18, air ≈ 1.005, oils ≈ 1.8–2.1 kJ/(kg·°C).
- Enter the Inlet and Outlet Temperatures in °C to define the sensible heat duty.
- If a phase change occurs (condensation, vaporization), enter the Heat of Phase Change in kJ/kg and the Phase Change Mass in kg/hr — set to 0 if there is no phase change.
- Read the Total Heat Duty in kJ/hr and Power Required in kW to size heaters, coolers, or heat exchangers.
- Compare Sensible Heat and Latent Heat contributions to understand which dominates the design.
