A closed square tank with a base of 0.6 m and a height of 3 m weighing 6000 N has a side hole with an effective area of 8 cm2 , 10 cm above the tank bottom, as shown in Figure P5.37. The tank is filled with water to a depth of 2.5 m and the coefficient of friction between the wheels of the tank and the ground is 0.015. Determine the pressure needed on the water surface to move the rank if the wheels are locked.
