A fireman wants to extinguish a fire at a height of 6 m above the nozzle standing at a distance 5 m away from the fire. Find ) minimum velocity of nozzle discharge required at an angle of 70°, velocity of discharge if he could extinguish with an angle of projection of 60°. 6 m Nozzle 5 m ANS: ) v = m/s (i) v = m/s (two decimal places)
