Initial Pressure according to Polytropic Process Solution

STEP 0: Pre-Calculation Summary

Formula Used

Initial Pressure of System = (Atmospheric Pressure*Density 1^Constant a)/Density of Fluid^Constant a
P_i = (P_atm*ρ₁^a)/ρ₀^a
This formula uses 5 Variables

Variables Used

Initial Pressure of System - (Measured in Pascal) - Initial Pressure of System is the total initial pressure exerted by the molecules inside the system.
Atmospheric Pressure - (Measured in Pascal) - Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth.
Density 1 - (Measured in Kilogram per Cubic Meter) - Density 1 is defined as the density of the fluid at point 1.
Constant a - The Constant a refers to the empirical constant given according to conditions in sutherland equation.
Density of Fluid - (Measured in Kilogram per Cubic Meter) - The Density of Fluid is its mass per unit volume, measuring how closely packed its particles are.

STEP 1: Convert Input(s) to Base Unit

Atmospheric Pressure: 350 Pascal --> 350 Pascal No Conversion Required
Density 1: 500 Kilogram per Cubic Meter --> 500 Kilogram per Cubic Meter No Conversion Required
