Water flowing in a smooth 6-cm-diameter pipe enters a venturi contraction with a throat diameter of 3 cm. upstreampressure is 120 kpa. if cavitation occurs in the throat at a flow rate of 155 gal/min, what is the estimated fluid vaporpressure. assuming ideal frictionless flow? (a) 6 kf‘a,(bl 12 kpa.(c) 24 kpa,(m 31 kpa.(e) 52 kpa
