Consider the venturi tube of Sample Problem 14.21 and Fig.without the manometer. Let A equal 5a. Suppose the pressure `p_(1)` at A is 3.0 atm. Compute the values of (a) the speed V at A and (b) the speed vat a that make the pressure `p_(2)` , at a equal to zero. (c) Compute the corresponding volume flow rate if the diameter at A is 5.0 cm. The phenomenon that occurs at a when p, falls to nearly zero is known as cavitation. The water vaporizes into small bubbles.

Explanation

(a) 5.0 m/s (b) 25 m/s (c) `2.0 xx 10^(-3) m^(3)//s`
