What is the equation of convection of heat transfer?

The equation for convection can be expressed as: q = hc A dT (1). where. q = heat transferred per unit time (W, Btu/hr). A = heat transfer area of the surface (m2, ft2). hc = convective heat transfer coefficient of the process (W/(m2oC, Btu/(ft2 h oF)). read more

Convective Heat Transfer Coefficient for Air. The convective heat transfer coefficient for air flow can be approximated to . h c = 10.45 - v + 10 v 1/2 (2) where . v = relative speed between object surface and air (m/s) Note! - this is an empirical equation and can be used for velocities 2 to 20 m/s. read more

Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids. Convection is usually the dominant form of heat transfer in liquids and gases. read more

Heat Convection Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. read more
