The unit of overall coefficient of heat transfer is

Question

RRB Paper · Accepted Answer

The overall heat transfer coefficient (U) depends on individual heat transfer coefficients and the heat resistance offered by the tube wall. The metric unit of the overall coefficient of heat transfer is kilocalorie per hour per square meter per degree Celsius (kcal/h·m²·°?) The SI unit of the overall coefficient of heat transfer is W/(m2K).
