Cavity fluid pressure - thermal expansion
Cavity fluid pressure - thermal expansion
(OP)
Given an oil-filled cavity that is heated, how can I find the oil pressure after thermal expansion?
I have CTE and original/ending volumes, just don't remember hwo to calculate pressure on the seal....trying to calculate whether seal with break.

RE: Cavity fluid pressure - thermal expansion
Change in Volume / Original Volume = Change in Pressure / Bulk Modulus
Dp = (Dv/V)*K = K* (Af -At)*DT
Af = Fluid Thermal Expansion Co-efficient
At = Tubing Thermal Expansion Co-efficient
K = Fluid Bulk Modulus
