Which one of the following expressions is equal to the pressure difference between Point c and Point d?
A. ρgas*g*v
B. ρgas*g*y
C. ρliquid*g*v
D. ρliquid*g*y Correct Answer
From dimensional analysis you know that A and C are incorrect. But how do you find the answer to be D? I was trying to do this question using the pressure of the atmosphere pushing down on point D and the gas from the right end pushing down on point C but I couldn't come up with the right expression.
