Heat kw
WebThe heat load of a heat exchanger can be derived from the following two formulas: 1. Heat load, Theta and LMTD calculation Where: P = heat load (btu/h) m = mass flow rate (lb/h) cp= specific heat (btu/lb °F) δt = temperature difference between inlet and outlet on one side (°F) k = heat transfer coefficient (btu/ft2h °F) A = heat transfer area (ft2) WebThe correct unit here is BTU/h. kW, on the other hand, stands for kiloWatt. Watt is the basic unit of power (in the metric system Europeans use), and it’s basically the amount of power …
