A fire-brigade man is holding a fire stream nozzle of 5 cm diameter as shown in Fig. The jet issues out with a velocity 13 m/s and strikes the window. Find the angle or angles of inclination with which the jet issues from the nozzle. What will be the amount of water falling on the window?
  • a)
    θ = 78.8°; Q = 0.0255 m3/s
  • b)
    θ = 61.9°; Q = 0.0255 m3/s
  • c)
    Both (A) and (B)
  • d)
    None of the above
Correct answer is option 'C'. Can you explain this answer?

Corresponding to nozzle exit, the co-ordinates of the point P where the jet strikes the window are: x = 5 m and y = 7.5 − 1.5 = 6 m (i) The path of trajectory is prescribed by the equation,
(ii) Amount of water falling on the window equals the amount delivered by the nozzle
