Consider the Venturi tube of Figure. Let area `A` equal `5a`. Suppose the pressure at `A` is `2.0 atm`. Compute the values of velocity `v ` at `'A'` and velocity `v` at `'a'` that would make the pressure `p'` at `'a'` equal to zero. Computer the corresponding volume flow rate it the diameter at `A` is `5.0 cm`. (The phenomenon at a when `p'` falls to nearly zero is known as cavitation. The water vaporizes into small bubbles.)
`(P_(atm) = 10^(5)N//m^(2), rho = 1000 kg//m^(3))`.

Text Solution

Verified by Experts

The correct Answer is:
`v = (10)/(sqrt(6))m//s = 4.1 m//s ; v' = (50)/(sqrt(6))m//s = 21 m//s;`
`Av = 8.1 xx 10^(-3) m^(3)//sec`
