A cooling water system uses a horizontal venturi with a differential pressure flow detector to provide flow rate indication.
Water enters and leaves the venturi at 70°F, 100 psig, and 24 ft/sec.
Water velocity at the throat of the venturi is 50 ft/sec.
Assume water is incompressible and the venturi experiences no unrecoverable head loss.
What is the approximate pressure of the water at the throat of the venturi?
A. 98 psig
B. 94 psig
C. 87 psig
D. 74 psig
