8. Two smooth rubber-lined fire hose each 90 m long and having a 25 mm diameter nozzles, are connected to a 150 mm fire hydrant. Cc 1.0 and Cv = 0.97. It is necessary to throw streams 24 m high, the nozzles being 6 m above the hydrant. Determine the horsepower that must be supplied at the hydrant. f = 0.023. Note: energy loss at the pipe is hf = fLV2/D2g or 0.0826fLQ²/D5 8 HA 56.45 m Q=0.0213 m³/s HP = 15.8 hp 90 m 60 mm o 24 m 6 m
