Determine the pressure as a function of depth

Assignment Help Mechanical Engineering
Reference no: EM13906794

An empirical formula relating pressure and density for seawater w/ temperature held constant is:

p/pa = (k+1)(q/qa)^7 - k

where p= pressure

pa = pressure at the surface

k = dimensionless constant

q = density

qa = density at the surface

Using the formula in the hydrostatic relation, determine the pressure as a function of depth.

The hydrostatic relation is: p+dgz=constant

I am uncertain as to the proper approach for beginning this problem. I know that if I wanted to take the derivative of the empirical formula there must be a z term. I tried to insert P/RT in for q (q=P/RT) and then substitute for T with the relation T=T0-kz. But I wasn't for sure where to go from there.
