Question

The figure Tank3png shows a water tank where a wall is a vertical flat-plate that is composed of two rectangular faces of areas Ai and A2 with widths w 1.0 m, W2 2.0 m respectively, and one semicircular face of area A3, with radius R 0.5 m. The dimensions h 1.0 m, h2- 1.0 m, as shown in the figure. The density of water, p -103kg/m3, acceleration due to gravity, g = 10 m/s The figure 4 shows a water tank where a wall is a vertical flat-plate that is composed of two rectangular faces with areas Al = 1.0 m, A2-2.0 m, and one semicircular face, A3, with radius R 0.5 m. The dimensions h 1.0 m, h2 1.0 m, as shown in the figure. The density of water, p 103 kg/m3, acceleration due to gravity, g 10 m/s2 Find the average pressures in N/m on the areas A1, A2, and A respectively: P1,avg and P3 avg The total hydrostatic force on the wall in iS The total hydrostatic force on the wall irn N is The depth in m, of the centroid of the entire plate is If some water is drained from the tank so that the depth of the water in the tank is reduced to the mid-level of the top rectangular section, i.e. now hi 0.5 m, The depth of the centroid in m, from the top of the water-line is , the average pressure on the wall in Nmis , and the total hydrostatic force in N on the tank wall is Tank Wall Face View of Tank Wall Area- A Avg Pressàre Pvh Water Area L A Avg Pressure P h2 Areal-A3 Avg Pressure h,- radius, R t.
