From the table above the heat transfer coefficient is 170 W/m2 oC for "Steam to Light Oil, Natural Convection". The heat transfer can be calculated as Q = (1.89 m2) ((120 oC) - (50 oC)) (170 W/m2 oC) = 22491 W
View MoreThe 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 …

View MoreThe overall heat transfer coefficient is related to the total thermal resistance and depends on the geometry of the problem. For example, heat transfer in a steam generator involves convection from the bulk of the reactor coolant to the steam generator inner tube surface, conduction through the tube wall, and convection (boiling) from the outer tube surface to the secondary side fluid.
View MoreIn cases of combined heat transfer for a heat exchanger, there are two values for h. There is the convective heat transfer coefficient (h) for the fluid film inside the tubes and a convective heat transfer coefficient for the fluid film outside the tubes. The thermal conductivity (k) and thickness (Δx) of the tube wall must also be accounted for.
