Question

Fire is caught at a height of 125 m from the fire bridge to extinguish the fire water is coming out from the pipe of cross section

Answer 1

Answer:

The minimum velocity of water exiting from fire bridge is 50 m/s.

(4) is correct option.

Explanation:

Given that,

Height = 125 m

Flow rate = 950 litre/min

Cross section of pipe = 6.4 cm

We need to calculate the minimum velocity of water exiting from fire bridge

Using equation of motion

Put the value in the equation

Hence, The minimum velocity of water exiting from fire bridge is 50 m/s.
