Heat transfer takes place through conduction, convection, and radiation. This easy-to-use series of calculators will quickly let you calculate basic heat transfer rates as well as rates for both conduction and convection. Calculate free convection by entering the surface area, heat transfer coefficient, and surface and fluid temperatures.

The heat transfer coefficient or convective coefficient (h), is used in thermodynamics to calculate the heat transfer typically occurring by convection. A simple way to calculate h is to define it through the classical formula for convection, and compare it with a different definition of h, through dimensionless parameters.

Heat transfer is a process is known as the exchange of heat from a high-temperature body to a low-temperature body. As we know heat is a kinetic energy parameter, included by the particles in the given system. As a system temperature increases the kinetic energy of the particle in the system also increases.
