A rectangular plate surface 3m wide and 5m deep lies in fluid of specific gravity .9 such that its plane makes an angle of 45⁰ with water surface, upper edge 3m below free water surface. Determine the total pressure.
(a) 86.5 N/cm^2
(b) 173 N/cm^2
(c) 43.25 N/cm^2
(d) None of the mentioned
I had been asked this question by my college professor while I was bunking the class.
Question is taken from Horizontal and Inclined Plane Surface Submerged in a Liquid in chapter Hydrostatic Forces on Surfaces of Fluid Mechanics
