An engine cooling system consists of the following components and associated losses; Engine Block and Head, HL=12.2m Radiator, HL=15.3m 5 x Elbows, C=1.3 3 x Junctions, C_=1.2 3 Meters of piping, C = 9.5 x 10-3, Diameter = 40mm Given that the flow rate of coolant through the cooling system is 50L/min determine the total head loss associated with the system. Take the density of water to be 1000kg/m3 and g = 9.81 m/s?. Select one: Oa. 31.79m O b. 29.79m O c. 27.79m O d. 25.79m

please write clearly if handwritten so that I could read and understand the solutions and steps taken

Figure 8.18 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 water to vaporize. The pressure at point B just ahead of the nozzle must be 25.0 psig for proper nozzle performance. The pressure at point A (the pump inlet) is -3.50 psig. The volume flow rate is 0.50 ft/s. The dynamic viscosity of the fluid is 4.0 x 105 lbs/ft². The specific gravity of the fluid is 1.026. Compute the power delivered by the pump to the fluid, considering friction energy loss in the discharge line.
