the geometry of the system, and the properties of the fluid. The coefficient of heat transfer and
thermal resistance are important parameters for determining the rate of heat transfer.
The amount of heat transferred in free and forced convection can be calculated using various laws,
such as Newton's law of cooling or the Stefan-Boltzmann law. The coefficient of heat transfer
is a parameter that relates the rate of heat transfer to the temperature difference and plays a
critical role in determining the amount of heat transferred.
Overall, the choice of heat transfer mechanism may depend on factors such as the geometry of the
system, the available resources, and the efficiency of the heat transfer process. The rate of heat
transfer in both free and forced convection can be increased by increasing the velocity of the
fluid, reducing the
thermal resistance, and increasing the surface area of the system.
