Problem 1.326

On the opposite sides of a wide vertical vessel filled with water two identical holes are opened, each having the cross-sectional area \(S=0.50 \mathrm{~cm}^{2}\). The height difference between them is equal to \(\Delta h=51 \mathrm{~cm} .\) Find the resultant force of reaction of the water flowing out of the vessel.
