Question:-
A cylindrical gate is holding water on one side as shown in the given figure. The resultant vertical component of force of water per meter width of gate will be

Option (A)
Zero
Option (B)
7700.8 N/m
Option(C)
15401.1 N/m
Option(D)
30803.4 N/m
Correct Option:
(C)
Question Solution:
Vertical forces = weight of fluid corresponding to semi circular volume
= w(pR2L/2) = 9.81 x 1000 x (p x (2)2 / (4 x 2)) x 1
= rg (pR2L/2)
= 15401.1 N/m
