Gap length Solution

STEP 0: Pre-Calculation Summary

Formula Used

Gap Length = Outer Radius-Inside Radius
L_g = r₂-r₁
This formula uses 3 Variables

Variables Used

Gap Length - (Measured in Meter) - Gap Length is the distance between two surfaces or gap.
Outer Radius - (Measured in Meter) - Outer Radius is a straight line from the centre to the outer circumference of a circle or sphere.
Inside Radius - (Measured in Meter) - Inside Radius is a straight line from the centre to the inner circumference of a circle or sphere.

STEP 1: Convert Input(s) to Base Unit

Outer Radius: 0.02 Meter --> 0.02 Meter No Conversion Required
Inside Radius: 0.01 Meter --> 0.01 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

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.

How to Calculate Gap length?

Gap length calculator uses Gap Length = Outer Radius-Inside Radius to calculate the Gap Length, The Gap length formula is defined as the distance between two concentric spheres in free convection or the difference between the inside and outside radius. Gap Length is denoted by L_g symbol.

How to calculate Gap length using this online calculator? To use this online calculator for Gap length, enter Outer Radius (r₂) & Inside Radius (r₁) and hit the calculate button. Here is how the Gap length calculation can be explained with given input values -> 0.01 = 0.02-0.01.

FAQ

What is Gap length?

The Gap length formula is defined as the distance between two concentric spheres in free convection or the difference between the inside and outside radius and is represented as L_g = r₂-r₁ or Gap Length = Outer Radius-Inside Radius. Outer Radius is a straight line from the centre to the outer circumference of a circle or sphere & Inside Radius is a straight line from the centre to the inner circumference of a circle or sphere.

How to calculate Gap length?

The Gap length formula is defined as the distance between two concentric spheres in free convection or the difference between the inside and outside radius is calculated using Gap Length = Outer Radius-Inside Radius. To calculate Gap length, you need Outer Radius (r₂) & Inside Radius (r₁). With our tool, you need to enter the respective value for Outer Radius & Inside Radius and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
