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. [1 mark] (b) Vertical height from free surface to center of pressure. [4 marks) (c) Inclined distance at centroid from free surface. [10 marks) (d) The resultant hydrostatic force acting on the flat plate.
