h = 10 ft
RHO = 10 ppg (or pounds/gallon)
P = 0.052 * RHO * h
P = RHO * G * h
I am very confused right now as why each equation gives a different answer! What are the correct units for the 2nd equation and how do I convert from second equation to the first one? And where does the g goes?! I looked it up online and but they just say "RHO" takes care of it! What does that mean?!
