I have a query regarding internal doors, should these be in the calculation if the rooms at either side of the doors are the same temperature? Hope this helps wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. 1. The parameters that need input values are the mass flow rate, specific heat, inlet temperature and outlet temperature of one of the fluids; the heat capacity, inlet temperature and outlet temperature of the second fluid; and an estimated value for the overall heat transfer coefficient. It produces a breakdown and total of the surface and ventilation heat losses for a specific room in kW (Kilowatts) and BTUs (British Thermal Units). So, all you have to do is to enter the water flow rate either in gpm, m3/hr or l/s and the calculator will show you the appropriate pipe size in mm and inch. Excel calculators allow me to free up time to focus on important things that matter the most.. =
