2-Water from a firehose is being pumped from a lake 1.5 m below the ground level, and the fireman is holding the nozzle 1 m above the ground. If the pump increases the pressure by 207 kPa, and the head loss in the fire hose is 1.22 m: a) What velocity will the water have upon discharging from the nozzle (V2)? b) If the fireman held the nozzle vertically upward, how high would the water rise (Hv)(ignoring air drag)? c) If the nozzle is 2.5 cm in diameter, what is the discharge (Q) d) What is the power required to drive the pump (Pw) if it is 85% efficient? (Value 10 points).
