Atmospheric Pressure According to Polytropic Process

Go Atmospheric Pressure = (Initial Pressure of System*Density of Fluid^Constant a)/(Density 1^Constant a)

Initial Pressure according to Polytropic Process

Go Initial Pressure of System = (Atmospheric Pressure*Density 1^Constant a)/Density of Fluid^Constant a

Density According to Polytropic Process

Go Density of Fluid = Density 1*(Atmospheric Pressure/Initial Pressure of System)^(1/Constant a)

Initial Density According to Polytropic Process

Go Initial Pressure of System = Atmospheric Pressure*(Density 1/Density of Fluid)^Constant a

Temperature Lapse Rate

Go Temperature Lapse Rate = Specific Gravity of Fluid/Constant b*((Constant a-1)/Constant a)

Height of Fluid Column of Constant Specific Weight

Go Height of Fluid Column = Pressure of Gas/(Density of Gas*Acceleration due to Gravity)

Positive Constant

Go Constant a = 1/(1-Rate Constant*Temperature Lapse Rate/Specific Gravity of Fluid)

Adiabatic Exponent or Adiabatic Index

Go Adiabatic Index = Specific Heat at Constant Pressure/Specific Heat at Constant Volume

Temperature Lapse Rate Formula

Temperature Lapse Rate = Specific Gravity of Fluid/Constant b*((Constant a-1)/Constant a)
λ = G/b*((a-1)/a)

What is specific gravity?

It is defined as the ratio of the density of a given substance, to the density of water (H2O). Substances with a specific gravity greater than 1 are heavier than water, and those with a specific gravity of less than 1 are lighter than water.

How to Calculate Temperature Lapse Rate?

Temperature Lapse Rate calculator uses Temperature Lapse Rate = Specific Gravity of Fluid/Constant b*((Constant a-1)/Constant a) to calculate the Temperature Lapse Rate, The Temperature Lapse Rate (dT/dZ) is the rate at which an atmospheric variable, normally temperature in Earth's atmosphere, falls with altitude.
