4. Fluid Jet: Jet Pressure. A pump is operating at 700 hp for a 400gal/min (gallon per minute) flow-rate of a 12-ppg (Ibm per gallon) fluid. The diameter of the pipe (D) is constant. The diameter of the nozzle (exit, d) is 2.5 inches. The total pressure loss of the system (due to pipe friction, valve, and elbows) is estimated to be 1400psi. The elevation differences are z1=100ft and z2=10,000ft. (a) Determine the exitozzle pressure. (b) What would be the nozzle pressure without the pump? [1 slug =32.174 lbm;1 gallon =77/576ft3;1hp=550ftlbf/s;g= 32.174ft/s2] Ans. (a) 7827psi; (b) 4827psi
