Determine the total force, in kN, on the bottom of a 100 × 50 m swimming pool. The depth of the pool varies linearly along its length from 1 m to 4m. Also, determine the pressure on the floor at the center of the pool. In kPa, the atmospheric pressure is 0.98 bar, the density of the water is 998.2 kg/m3. And the local acceleration of gravity is 9.8 m/s2.
