Situation: Cavitation in a venturi section. D = 50 cm, d = 10 cm. Find: Discharge for incipient cavitation. Or, At what Q does cavitation occur? Properties: Water (10°C), Table A.5: p= 1000 kg/m³. PA = 130 kPa, Patm = 100 kPa abs. Vapor Pressure of Water = 1,230 Pa Pt A D d Note: Cavitation occurs when the pressure at the throat equals the vapor pressure.

Expert Solution
Step 1

Given:-

The diameter of the venturi meter = D = 50 cm = 0.50 m

The diameter of the throat = d = 10 cm = 0.10 m 

The pressure at point A = PA = 130 kPa

The density of the water at 10° C = 1000 kg/m3

The atmospheric pressure = Patm = 100 kPa

The vapor pressure of the water = 1230 Pa

To determine:-

The discharge for incipient cavitation
