According to P1V1/T1=P2V2/T2, when the temperature change is small, it is considered a constant value. Calculate the gas volume, divide it by 30 minutes to obtain the flow rate, and use this value to select pipes, valves, etc.
Based on the formula P1V1=P2V2, it is impossible to fill a 1000 cubic meter tank at 0.4 MPa with gas under pressure of 77 cubic meters at 30 MPa; 77*30/0.4=5775 m3
Personally, I agree with what was said above...
Sorry, it’s 3.0 MPa, 3# zjs0536
What is the initial pressure inside the tank? Another point is how the temperature of the medium inside the tank changes How is temperature change calculated?
