Given, flow rate = 3m3/s

To determine the cross-sectional area of the grit chamber, we need to use the formula:

Q = A×V

where Q is the flow rate, A is the cross-sectional area, and V is the velocity of flow.

Assuming a velocity of 0.3 m/s for grit particles, we can calculate the required cross-sectional area as follows:

A = Q/V = 3/(0.3) = 10m2

Therefore, the correct answer is option B, 10m2.

In the grit chamber, the flow velocity is maintained at 0.3 m/s.

Since Q=VA
Surface area of the chamber = Q/V
= 3/0.3 = 10 m2
