Re: Need Help with an Air Tank Problem

You should also know how many strokes you have in a min or hour? So you calculate a needed flow as a volume of the cylinder * number of strokes; Q = V * n, where is Q - is a flow, V - is volume, n - is a number of strokes in a unit of time. Another question is if you have a compressor to fill the ta...

Re: Gas Constant

It is not changing with the pressure or the temperature. It is constant for a certain gas. R in terms of J/kg K is calculated as Ru/M where Ru is universal gas constant for any gas and particular molar mass. Ru = 8.314 J/mol K. In your formula pV=nRT you are using Ru. in a pV=mRT or p/rho = RT formu...

Re: Pressure drop Calculation.

First, you have to enter absolute, not gauge pressure.
Check the pipe diameter that you are entering, as well as critical pressure and temperature for LPG.
Also, select to enter w (on the right side of the calculator) and then enter mass flow rate.
Hope this helps.
