Q:

Suppose that you have an opened cylinder filled to the top with two equal quantities of fluids. Fluid A has a density of a and Fluid B has a density of b. If the height of the cylinder is x, what is the pressure of the fluid system at the bottom of the cylinder (assume that atmospheric pressure is P_atm and that gravity is g)?

A

(bgx)/2 + (agx)/2

B

(bgx)/2 + agx

C

P_atm + (bgx)/2 + agx

D

P_atm + (bgx)/2 + (agx)/2
