Q1:

For a grit chamber, if the recommended velocity of flow is 0.2 m/sec and detention period is 2 minutes, the length of the tank, is

A 16 m

B 20 m

C 24 m

D 30 m

ANS:C - 24 m

Length=Velocity×Detention TimeLength=Velocity×Detention Time Given:

  • Recommended velocity of flow (V) = 0.2 m/sec
  • Detention period (T) = 2 minutes = 2 × 60 seconds = 120 seconds
Substitute the given values into the formula: Length=0.2 m/sec×120 seconds=24 metersLength=0.2m/sec×120seconds=24meters So, the length of the grit chamber is 24 meters.
