B3. A rectangular plate of width 45 mm, depth =60 mm is vertically placed in water in such a way that the centre of the plate is 3.25 m below the free surface of water. Draw the diagram neatly. Find the total pressure & center pressure on the plate.

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)

Question 1 . Find the pressure force and the acting point to the rectangular gate fort the waters depths 3 and 6 m. Gate is 5 m width. Draw the pressure diagrams. 3m 3m KIIII Gate 3m

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.

QUESTION 3: An inclined semicircular-shaped (diameter = 7 m) flat plate is entirely submerged in coconut oil (SG = 0.903). The angle between the free surface and the plane of the surface is 47°. Given the hydrostatic P (Pgauge) acting on center of pressure was 73.2 kPa. Assume the both sides of the plate are subjected to Patm. Calculate the: -Line of action F=PA Center of pressure Centroid of area (a) Density of coconut oil. (b) Vertical height from free surface to center of pressure. (c) Inclined distance at centroid from free surface. (d) The resultant hydrostatic force acting on the flat plate.
