A cylindrical water tank of height 6.0 m is completely filled with water. At the base of the tank there is a square inspection hatch of side 0.50 m that lies horizontal.
(i) Calculate the gauge pressure acting on the outer face of the hatch.
(ii) Determine the absolute pressure acting on the hatch. Take atmospheric pressure as 1.01×105Pa.
(iii) Find the total force exerted by the water on the hatch.
