Mass Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mass Velocity = Mass Flow Rate/Cross Sectional Area
G = ṁ/A_T
This formula uses 3 Variables

Variables Used

Mass Velocity - (Measured in Kilogram per Second per Square Meter) - Mass Velocity is defined as the weight flow rate of a fluid divided by the cross-sectional area of the enclosing chamber or conduit.
Mass Flow Rate - (Measured in Kilogram per Second) - Mass flow rate is the mass of a substance that passes per unit of time. Its unit is kilogram per second in SI units.
Cross Sectional Area - (Measured in Square Meter) - Cross sectional area is the area of a two-dimensional shape that is obtained when a three dimensional shape is sliced perpendicular to some specified axis at a point.

STEP 1: Convert Input(s) to Base Unit

Mass Flow Rate: 133.9 Kilogram per Second --> 133.9 Kilogram per Second No Conversion Required

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 Velocity?

Mass Velocity calculator uses Mass Velocity = Mass Flow Rate/Cross Sectional Area to calculate the Mass Velocity, The Mass Velocity formula is defined as the ratio of Mass flow rate to the cross sectional 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 Velocity is denoted by G symbol.

How to calculate Mass Velocity using this online calculator? To use this online calculator for Mass Velocity, enter Mass Flow Rate (ṁ) & Cross Sectional Area (A_T) and hit the calculate button. Here is how the Mass Velocity calculation can be explained with given input values -> 13 = 133.9/10.3.

What is Mass Velocity?

The Mass Velocity formula is defined as the ratio of Mass flow rate to the cross sectional 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 and is represented as G = ṁ/A_T or Mass Velocity = Mass Flow Rate/Cross Sectional Area. Mass flow rate is the mass of a substance that passes per unit of time. Its unit is kilogram per second in SI units & Cross sectional area is the area of a two-dimensional shape that is obtained when a three dimensional shape is sliced perpendicular to some specified axis at a point.
