Q: What causes cavitation?
A: Cavitation occurs when water changes its state from vapour to water at low pressure.
Q: What causes cavitation?
A: Cavitation occurs when water boils at 100°C and changes its state from water to vapour at normal atmospheric pressure.
01: Cavitation occurs when water changes its state from vapour to water at low pressure.
02: Cavitation occurs when water boils at 100°C and changes its state from water to vapour at normal atmospheric pressure. Your answer
03: Cavitation occurs when water flows through a pipe and a valve is closed quickly at a low atmospheric pressure
