What are some Important Formulas for Heat Transfer?

Some important formulas for heat transfer include the equations for conduction, convection, and radiation. The heat transfer rate by conduction is given by Q = kA (T2-T1)/d, where k is the thermal conductivity of the material. The heat transfer rate by convection is given by Q = hA(Ts - Tf), where h is the heat transfer coefficient. The Stefan-Boltzmann law gives the total radiant heat energy emitted per unit time per unit of surface area.

How is heat transfer coefficient defined in convection?

The heat transfer coefficient in convection is defined as the ratio of the heat transfer rate to the product of the surface area and the temperature difference between the surface and the fluid. It is denoted by h and is expressed in units of W/(m2.K).

What is the Stefan-Boltzmann law?

The Stefan-Boltzmann law is a formula that describes the rate at which thermal radiation is emitted from a body. It states that the total radiant heat energy emitted per unit of time per unit surface area is proportional to the fourth power of the absolute temperature of the body.

How is heat transfer rate defined in radiation?

In radiation, the heat transfer rate is defined as the amount of heat transferred per unit of time per unit surface area due to thermal radiation. It is given by the Stefan-Boltzmann law, which relates the heat transfer rate to the surface temperature and emissivity.

What is the formula for heat transfer by forced convection?

The formula for heat transfer by forced convection is given by Q = hA(Ts - Tf), where Q is the heat transfer rate, h is the heat transfer coefficient, A is the surface area, Ts is the surface temperature, and Tf is the temperature of the fluid.
