subjected to pressure of liquid of specific gravity 1.40 on one side. The free surface of the liquid is 2.60 m above the uppermost part of the gate. Calculate

A 10000 litre water tank is placed on a building roof and filled to capacity.  The empty tank has a mass of 550kg.  It is supported on 4 feet, each of which is a 300 x 300 mm steel plate.  What is the pressure exerted by each plate, in Pa?  (Round your answer to 2 significant figures)

Consider the pressure and force acting on the pool retaining a reservoir of water. Suppose the pool is 50m wide and the water is 8m deep, as illustrated below.   (a) What is the Gauge pressure on the dam due to the water?   (b) What is the absolute pressure at10m depth of the dam?   (C) Calculate the force exerted against the dam. Density of water is 1000kg/m3.
