Fluid calculation - Pressure increase for volume reduction

[Guffy]

I'm in a bit of bind tonight...

Can someone help with a formula for calculating an increase in fluid pressure (psi) for a reduction in volume (in3)?

i.e. Compressing a fluid with an SG of 1.35 and a volume of 7535in3 by 2.35in3

Google is not my friend!!

Before i get my calculations book out from work

Why are you compressing the liquid?

I thougth for all intents and purposes, liquids are incompressible?

Go to google books. Type in liquid compressibility factor and you get Theoretical and computational dynamics of a compressible flow
By Shiyi Bai, Shijun Luo.

Page 24 explains it very simply.

Hope this helps.

How about Ideal gas laws? PV=nRT
P = Pressure
V = Volume
n = the amount of substance
R = 8.314472 J·K−1·mol−1
T = Temp in Kelvin

Where Density and M molar mass are used.
