A (150 mm x150 mm) square pillar is located in a river with water flowing at a velocity of 2 m/s, as shown in figure. The height of the pillar in water is 8 m. Take density of water as 1100 kg/m and kinematic viscosity as 1.5 x 10-6 m/s?. The coefficient of drag of the pillar is 2.0. The drag force exerted by water on the pillar in N is 150 mm 2 m/s 150 mm 8 m A (150 mm x150 mm) square pillar is located in a river with water flowing at a velocity of 2 m/s, as shown in figure.
