What Is The Physical Significance Of Prandtl Number? Prandtl number signifies the thickness of thermal boundary layer and thickness of hydrodyanamic boundary layer, depending on whether it is equal to one, or more than one or less than one. If it is equal to one, it signifies that thickness of thermal boundary layer is equal
What Is The Physical Significance Of The Nusselt Number Please Defined It? Nusselt number represents the ratio of heat flux by fluid when heat is transferred What is the physical significance of the Nusselt number how is it defined? Nusselt number for a flow system gives basic difference between convection and conduction heat transfer. For
What Are Boundary Conditions Heat Transfer? Surface-based heat transfer boundary conditions represent either a known physical state, such as temperature, or an amount of heat entering or leaving the device, such as a heat flux. Temperature is the only condition that can be applied to openings and wall surfaces. You should apply the others only
What Is The Correct Direction Of Heat Transfer? And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation. Sometimes more than one may occur at the same time.
