Determine the anchoring forces Rx and Ry required to hold in place a conical nozzle at the end of hose when the water flowrate is 50 L/min. The nozzle is oriented at a 45 degree angle as shown below. Assume that the water has a density of 1000 kg/m3. The pressure in section 1 is 1000 kPa. Ignore the contribution of the weight of the nozzle and weight of the liquid in the nozzle. Assume P2 = 0.
