Seek help: DN20 diameter, 2.0 Mpa, natural gas flow rate

Thread Content

I need help determining how many cubic meters of gas can pass per second through a valve when it is fully open, under conditions of a pipe diameter of DN20, a pressure of 2.0 Mpa, with standard natural gas as the fluid and a temperature of 10°C, with the gas being discharged into the atmosphere.

No one can calculate this estimate!

This flow rate decreases gradually, so only instantaneous values can be calculated!

You need to know the volume to do that! How can you calculate it without volume?
