To get started, I'd suggest the latest edition of Perry's for the basics. For relief work, we use the Homogeneous Equilibrium Model where I work.
Good luck,

Let's say you use the homogeneous equilibrium model and it estimates the dP = 18 psi. For 95% confidence limits on the *actual* dP, the lower limit = 18/1.8 = 10 psi and the upper limit = 18x1.8 = 32 psi. So, you can be 95% confident the actual dP is going to be between 10 to 32 psi. Not too accurate, huh?
Good luck,
