Maintaining the proper flow in a heat transfer system is very important to ensure that the correct amount of heating or cooling gets to where you need it. This series of calculators can output a range of fluid data including average flow velocity, volumetric flow rate, and pipe inside diameter. You can select to use either our metric or imperial versions depending on your needs. Data is accurate to within two decimal places.
