Problem 1.328

Water flows out of a big tank along a tube bent at right angles; the inside radius of the tube is equal to \(r=0.50 \mathrm{~cm}\) (Fig. 1.87 ). The length of the horizontal section of the tube is equal to \(l=22 \mathrm{~cm}\) The water flow rate is \(Q=0.50\) litres per second. Find the moment of reaction forces of flowing water, acting on the tube's walls, relative to the point \(O\).
