Being able to efficiently add or remove heat is the primary function of a thermal fluid. The heat transfer coefficient is the calculated amount of heat that passes between the thermal fluid to or from any given surface it comes in contact with by way of convection – with the driving force behind the transfer of heat being the temperature differential between the two. This calculator will help estimate your heat transfer coefficient, pressure drop and Reynolds number for a basic pipe or tube model.
