Heat Transfer Calculator

Heat transfer rate refers to the rate at which heat energy is transferred from one body to another. The rate of heat transfer is determined by several factors, including the specific heat capacity of the materials involved and temperature difference. This heat transfer calculator calculates the heat transfer rate of a fluid in motion.

ExplanationThe heat transfer rate in a fluid in motion is calculated using mass flow rate, specific heat capacity and temperature difference. The specific heat capacity of a substance is a measure of the amount of heat required to raise the temperature of a given amount of the substance by one degree Celsius.
