5.36. A horizontal nozzle with an outlet diameter of 5 in is fitted into a 20-in-diameter pipe, as shown in Fig- ure P5.36. The pressure head at the nozzle inlet is 20 ft. Neglecting the head loss inside the nozzle and assuming that the weight of the nozzle and water in it is 250 Ib, what force is needed to hold the nozzle in the pipe?
