Thrust and Pressure

Pressure is

Assertion: Pascal law is the working principle of hydraulic lift. Reason: Pressure =(thrust)/(area)

Assertion: Pascal law is the working principle of hydraulic lift. Reason: Pressure =(thrust)/(area)

Assertion: Pressure can not be subtracted from pressure gradient. Reason: Pressure and pressure gradient have different dimensions.

Assertion: In the siphon shown in figure, pressure at P is equal to atmospheric pressure Reason: Pressure at Q is atmospheric pressure and points P and Q are at same levels.

Total pressure of a gaseous mix is equal to the sum of the Partial Pressures is:

The pressure of moist gas is higher than pressure of dry gas.

Thrust per unit area is called pressure.

A vessel of length l, breadth b and height h is filled completely with a liquid of density d (see figure) Calculate the thrust on each surface of the cube.
