What is Convection?

Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid. Convection is the process of heat transfer in fluids by the actual motion of matter. It happens in liquids and gases. It may be natural or forced. It involves a bulk transfer of portions of the fluid.

What are the Types of Convection?

There are two types of convection, and they are: Natural convection: When convection takes place due to buoyant force as there is a difference in densities caused by the difference in temperatures it is known as natural convection. Examples of natural convection are oceanic winds. Forced convection: When external sources such as fans and pumps are used for creating induced convection, it is known as forced convection. Examples of forced convection are using water heaters or geysers for instant heating of water and using a fan on a hot summer day.

How to Calculate Prandtl Number given Recovery Factor for Gases for Laminar Flow?

Prandtl Number given Recovery Factor for Gases for Laminar Flow calculator uses Prandtl Number = (Recovery Factor^2) to calculate the Prandtl Number, The Prandtl Number given Recovery Factor for Gases for Laminar Flow formula is defined as the square of recovery factor. In the actual case of a boundary-layer flow problem, the fluid is not brought to rest reversibly because the viscous action is basically an irreversible process in a thermodynamic sense. In addition, not all the free-stream kinetic energy is converted to thermal energy— part is lost as heat, and part is dissipated in the form of viscous work. To take into account the irreversibilities in the boundary-layer flow system, a recovery factor is defined. Prandtl Number is denoted by Pr symbol.

How to calculate Prandtl Number given Recovery Factor for Gases for Laminar Flow using this online calculator? To use this online calculator for Prandtl Number given Recovery Factor for Gases for Laminar Flow, enter Recovery Factor (r) and hit the calculate button. Here is how the Prandtl Number given Recovery Factor for Gases for Laminar Flow calculation can be explained with given input values -> 6.25 = (2.5^2).

FAQ

What is Prandtl Number given Recovery Factor for Gases for Laminar Flow?
The Prandtl Number given Recovery Factor for Gases for Laminar Flow formula is defined as the square of recovery factor. In the actual case of a boundary-layer flow problem, the fluid is not brought to rest reversibly because the viscous action is basically an irreversible process in a thermodynamic sense. In addition, not all the free-stream kinetic energy is converted to thermal energy— part is lost as heat, and part is dissipated in the form of viscous work. To take into account the irreversibilities in the boundary-layer flow system, a recovery factor is defined and is represented as Pr = (r^2) or Prandtl Number = (Recovery Factor^2). Recovery Factor is a dimensionless number defined by the ratio of difference in enthalpies.
