Question

1.     A large diameter water tank is open to atmospheric pressure at 100 kPa. The water level is 20 meters above the venture outlet. The water is drained from the bottom of the tank with a pipe. A venture is located in the pipe as shown with an outlet to throat area ratio of 1.2. what is the pressure at the venture throat in kPa assuming no frictional head loss? (hint. Solve Bernoulli for exit velocity. Then apply Bernoulli between throat and exit to find throat pressure.)

a.     5

b.     19.8

c.      91.0

d.     None of the above
