Consider the venturi tube of Problem and Figure without the manometer. Let A equal 5a. Suppose the pressure pt at A is 2.0 atm. Compute the values of
(a) The speed V at A and
(b) The speed v at that makes the pressure p2 at an 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 p2 falls to nearly zero is known as cavitations. The water vaporizes into smallbubbles.
