Problem 1.329

A side wall of a wide open tank is provided with a narrowing tube (Fig. 1.88) through which water flows out. The cross-sectional area of the tube decreases from $S=3.0 \mathrm{~cm}^{2}$ to $s=1.0 \mathrm{~cm}^{2}$. The water level in the tank is $h=4.6 \mathrm{~m}$ higher than that in the tube. Neglecting the viscosity of the water, find the horizontal component of the force tending to pull the tube out of the tank.
