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 Mass Flow Rate from Continuity Relation for One Dimensional Flow in Tube?

Mass Flow Rate from Continuity Relation for One Dimensional Flow in Tube calculator uses Mass Flow Rate = Density of Fluid*Cross Sectional Area*Mean velocity to calculate the Mass Flow Rate, The Mass Flow Rate from Continuity Relation for One Dimensional Flow in Tube formula is defined as the product of density, mean velocity and the area. Consider the flow in a tube. A boundary layer develops at the entrance, Eventually the boundary layer fills the entire tube, and the flow is said to be fully developed. If the flow is laminar, a parabolic velocity profile is experienced. When the flow is turbulent, a somewhat blunter profile is observed. In a tube, the Reynolds number is again used as a criterion for laminar and turbulent flow. Mass Flow Rate is denoted by ṁ symbol.
