Main Question or Discussion Point
I am trying to calculate pressure losses. I've attached an image to show what I mean. Starting out tank 1 is 92.8 litres at 155 psi and when the shutoff valve is open the volume goes from 92.8 to 192.8 and so I thought the pressure would drop by the same factor that the volume increased by so giving 74.59 psi in each tank (192.8/92.8=2.078 so 155/2.078=74.59). This is then fed into a larger tank and using the same method as before I worked out the pressure would be 17.63 psi. Is this the correct way to calculate pressure changes?
