A pipe of uniform correctional of area a has a right-angled bend, impure water of density δ δ flows through the horizontal portion of the pipe. The distance covered by water per second at the bend to keep the pipe in equilibrium against an applied force F at the bend is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Force × Time = Change in momentum
or F × Δ Δ t = Δ Δ mv √ √ 2 or F = 
= 
( Q Δ Δ m = ρ ρ a Δ Δ L)
or F = 
= v 2 
v =
