Did you calculate the pressure difference between two locations using the correct specific weight?
Did you assume that the pressures in fluid are the same in a horizontal plane even though they are in different tubes?
Are the calculated pressures in a column of fluid always higher at lower elevations?
Did you account for the fact that the two horizontal tubes of the U-tube are above the ground?
Concepts: The pressure in a fluid is a function of the specific weight of the fluid and the height relative to a reference.
Pressure is constant in a horizontal plane of a continuous mass of fluid.
(a) What is the initial pressure difference? (PA-PB)
(b) What is…
