angles of α = 60°, β = 120°, γ = 45°. Express the result as a Cartesian vector.
Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.

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.
