Cavity fluid pressure - thermal expansion

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

If the cavity is fixed volume, the pressure rise is in the order of 50 to 75 psi per deg F for an oil.

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




 

RE: Cavity fluid pressure - thermal expansion

Take a look at thread124-133483.

AMAZING, gentlemen. Thanks for your help.
