47. Total pressure on the top of a closed cylindrical vessesl completely filled with liquid, is directly proportional to

48.  A closed cylindrical vessel of 100 cm diameter and 200 cm high is completely filled with a liquid (sp. weight 1600 kg/m3) when rotated about its vertical axis at 100 r.p.m. The total pressure on its lid, is
