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.
a. (i) Calculate the gauge pressure acting on the outer face of the hatch.
b. (ii) Determine the absolute pressure acting on the hatch. Take atmospheric pressure as 1.01×105Pa.
c. (iii) Find the total force exerted by the water on the hatch.
