As shown in the figure, a can with a diameter of 60 [cm] with wheels is filled with water up to a height of 60 [cm]. When connecting a tube with a diameter of 1 [cm] and a length of 15 [cm] to a height of 10 [cm] from the bottom of the can and letting water flow out, find the thrust acting on the can. However, the loss other than the pipe friction at the straight pipe part of the outlet is negligible, the pipe friction coefficient is λ = 0.025, and the water density is ρ = 1000 [kg / m3]. In addition, the upper part of the can and the outlet of the straight pipe part are open to the atmosphere, and changes in the water level of the can and rolling resistance of the wheels are negligible.
