Homework Statement


a hydraulic system operates at 3000 psi. Compute the percentage change in the volume of the oil in the system as the pressure is increased from zero to 3000 psi if the bulk modulus of the oil is 189000 psi.


Homework Equations


E=∆p/(∆V)/V

The Attempt at a Solution


[itex]189 000 psi = -3000 psi/v[/itex]
=-63
which is way off.

ps. by the way is it possible to use the increment symbol (∆) in latex font?
