Question
Rain water is falling vertically downward with velocity u. When velocity of the wind is u blown in the horizontal direction, water is collected at the rate of Qm3/s. When the wind velocity in the horizontal direction is doubled, the rate of collection of water is :-
Options
A.Q
B.
C.
D.
Solution
The rain water collected per second depends upon the vertical component of velocity which remains unchanged with horizontal velocity of the wind. Hence, the rate of collection of water is still Q m3/s.
