Homework Statement
Hi guys,
My first post here, I hope someone can help me out with a quick fluid mechanics problem.
I'm looking to calculate the pressure increase inside a closed tube full of water when the tube is crushed and therefore its volume reduced.
The tube is filled completely with water and pressurised to a nominal pressure of 10 bar. The starting volume is 2.1l and the volume after crushing is 90% of the initial volume.
2. The relevant equations
The tube remains sealed at all times so I think I can consider the fluid to be static and as its water, incompressible. However im struggling to find the relevant equation to allow me to calculate the new pressure. All the static problems i have seen are concerned with open containers.
Can anyone help?
Thanks,
Chris
