Heat Transfer Calculator

The Heat Transfer Calculator is a free online tool that shows the rate at which heat transfers from one substance to another. This heat transfer calculator tool speeds up the process by displaying the heat transfer rate in a fraction of a second.

Heat Transfer Calculator: Heat is transferred through conduction, convection, and radiation. This simple calculator set will allow you to rapidly compute basic heat transfer rates, as well as rates for both conduction and convection. Enter the surface area, heat transfer coefficient, and surface and fluid temperatures to calculate free convection.

Heat Transfer Formula

The production, consumption, transformation, and exchange of thermal energy across physical systems is the subject of heat transfer, which is a branch of thermal engineering. Thermal conduction, thermal convection, thermal radiation, and energy transfer via phase shifts are all examples of heat transfer methods.

The equation for transferring heat from one system to another is as follows: Q = m×c×ΔT

  • Where, Q be the Heat transferred
  • M is the mass in kg
  • C be the specific heat
  • ΔT is change in tenperature

The transfer of heat energy or thermal energy from one substance to another at various temperatures is referred to as heat transfer. Also, take a look at Heat Energy.

It should be noted that heat can be transported in three ways, including:

  • Heat transmission from a high-temperature object to a low-temperature object is known as conduction.
  • Heat transfer from a high to a low temperature via fluid molecules is known as convection.
  • Heat is conveyed through electromagnetic radiations/waves, which is referred to as radiation.

Heat Transfer Calculation Examples

Question 1:A 5 kg system is heated from a initial temperature of 40 degrees Celsius to a final temperature of 50 degrees Celsius. Calculate the system's total heat output. It's worth noting that the system's specific heat is 0.35 kJ per Kg K.


Consider the question,

Initial temperature, Ti=40∘C

Final temperature, Tf=50∘C

Mass, m = 5 kg

We know that, The formula for finding the heat transfer is Q=m×c×ΔT

Q=m×c×( Tf– Ti)




Therefore,The heat transfer is Q = 17.5J.

FAQs on Heat Transfer Calculator

1. How can you figure out how much heat is transferred?

The process of transferring heat from one thing at a higher temperature to another object at a lower temperature is known as heat transfer. As a result, heat is a measure of the kinetic energy held by the particles in a system.

2. How do you go about finding the joules?

Work (joules) = force (newtons) x distance (metres), where a joule is defined in the next paragraph as the unit of work.

3. In terms of heat transfer, what is K?

The thermal conductivity constant is denoted by the letter k. For materials that transport heat well (such as metal and stone), the thermal conductivity constant k is higer, whereas for materials that transfer heat poorly, k is small (like air and wood).
