10. A fire pump delivers water through a 300 mm main hydrant to which is connected a cotton rubber-lined fire base 100 mm in diameter terminating in a 25 mm diameter nozzle (Cv = 0.98) Assuming friction lost in 300 mm pipe is 3.1 m, 2.5 m from the 100 mm , and 0.8 m from the reservoir to the pump. A) Compute the added energy produce by the pump if it delivers 20 L/s B) If the jet of the nozzle is thrown vertically, what is the maximum height that the water can reach? C) What is the pressure at the pump? EL 70 m 300 mm + EL. 5m 100 mm hydrant EL 20 m 25 mm nozzle) El 22 m
