A centrifugal pump with an impeller diameter of 0.18 m is to be used to pump water (ρ = 1000 kg/m³) with the pump inlet located 3.8 m above the surface of the supply reservoir. At a flow rate of 0.760 m³/s, the head loss between the reservoir surface and the pump inlet is 1.80 m of water. The performance curves are shown below. Would you expect cavitation to occur?
