I think it will be 2.5 m/sec.

Am I right?

Yes it is 2.5.

Ram Vilash said: (Sep 3, 2016)  
According to K.R Arora maximum velocity is 2.7 But in question 2.5 is most nearest to 2.7. Hence 2.5 is correct.

Absolutely right @CHANDAN. That is 2.5 m/s.

Lining material Limiting velocity (m/s).

Boulder ---> 1.0"1.5.
Brunt clay tile ---> 1.5"2.0.
Concrete tile ---> 2.0"2.5.
Concrete ---> 2.5"3.0.

For India, it should be 2 m/sec.

Boulder = 1.5,
Brunt clay tile = 1.8,
Cement concrete = 2 - 2.5,
Stone masonary = 1m/sec.

For precast cement, concrete velocity should not exceed 2 m/sec.

For cast in situ concrete, the velocity should not exceed 2.5 m/sec.

2.5 m/s should be the answer.
