Question

The sketch shows a system used to spray polluted water into the air to increase the water's oxygen content and to cause volatile solvents in the 6. water to vaporize. The pressure at B of the nozzle must be 25 psig for proper nozzle performance. The pressure at point A (the pump inlet) is -3.5 psig. The volume flow rate is 0.5 ft3/s. The dynamic viscosity of the fluid is 4.0 x 10 Ib-s/ft?. The specific gravity of the fluid is 1.026. Compute the powerH-Suale aD delivered by the pump in horse d pre power to the fluid, considering friction loss in the discharge line. 80 ft sol pipe Puap 뚱: 15- for cloe retuv1k bend 5 marks
