A stream of water flowing horizontally with a speed of v gushes out of a tube of cross-sectional area A, and hits a vertical wall nearby. The force of impact on the wall when the water does not rebounds is –
A
A v 2
B
A v 2 
C
A v 
D
A 
Text Solution
Verified by ExpertsThe correct answer is:
B
F = v. 
= v(A ρ v) = A ρ v 2
[Note: 
= mass flow rate = A ρ v]
