The discharge through a venturimeter is given as (with usual notations):
1
\(Q = ~\frac{{C_d}\space A_1^2\space A_2^2\space \sqrt {2gh}}{ \sqrt {A_1^2 - A_2^2} }\)
2
\(Q =~\frac{ {C_d}\space {A_1}\space {A_2}\space \sqrt {2gh}}{\sqrt {2A_1^2 - A_2^2}} \)
3
\(Q = \frac{{C_d}\space {A_1}\space {A_2}\space \sqrt {2gh}}{\sqrt {A_1^2 - A_2^2} }\)
4
None of the above
