Question

The volume of oil contained in a certain hydraulic press is 0.3m^3. Find the decrease in the volume of the oil when subjected to a pressure increase of 5.04x10^7 Pa. The compressibility of the oil is 10x10^-6 atm^-1.

I getting screwed up in my conversion from the compressibility to the Bulk Modulus. I know the formula to use is V = -V(original)P/B. I'm getting a B value of 0.9869, which gives me an answer of -1.53x10^7, which seems to be stupidly high. Someone else came up with a B value of 1.01325x10^10, but I can't figure out how.

Help?

Explanation / Answer

compressibility is just the inverse of the bulk modulus

find B and apply the formula

C = 1/B = 10x10^-6 atm^-1

=> B = 10^5 atm  =  10^10 N/m^2 ~ 1.01325x10^10 N/m^2

now i guess, u can solve..!!
