Cavitation is a phenomenon in fluid mechanics that can occur when a fluid is subjected to a decrease in pressure. When the pressure of the fluid decreases below the vapor pressure of the fluid, bubbles of vapor can form. These bubbles can collapse violently when they are subjected to an increase in pressure, causing damage to nearby objects.

Q: What is meant by cavitation in fluid mechanics?
A: Cavitation is a phenomenon that can occur in fluids when the fluid’s pressure drops below the vapor pressure of the fluid. This can happen when the fluid is flowing through a constriction, such as a pipe or valve. When cavitation occurs, bubbles can form in the fluid. These bubbles can then collapse, which can cause damage to nearby surfaces.
Q: What is cavitation and its types?
A: Cavitation is the formation of bubbles in a liquid due to the application of pressure. The pressure of the liquid must be lower than the vapor pressure of the liquid for cavitation to occur. Cavitation can occur in any type of liquid, but is most commonly seen in water.
There are two types of cavitation:
1. Vapor cavitation: This is when the bubbles are filled with vapor.
2. Liquid cavitation: This is when the bubbles are filled with liquid.
Q: What is cavitation and its effect?
A: Cavitation is the formation of cavities or voids in a liquid, and is a phenomenon that can occur in pumps, turbines, and other rotating machinery. When cavitation occurs, the liquid can collapse in on itself, creating a small vacuum. This can cause damage to the machinery as well as noise and vibration.
Q: What causes fluid cavitation?
A: Cavitation is caused by a decrease in fluid pressure. This can happen when the fluid is moving too quickly, or when there is a sudden change in pressure.
