In summary, the Q factor of a bowl of water is a measure of the damping or energy dissipation in a resonant system. It can be calculated by dividing the resonant frequency of the water by the bandwidth of the oscillations. Factors such as the shape, size, temperature, and viscosity of the water can affect the Q factor. It is important in understanding the properties and behavior of the water and has practical applications in engineering and design. The Q factor can be increased by minimizing external forces and optimizing the bowl's shape and size to achieve longer and more sustained oscillations.

Are you referring to surface waves of the water?
It would depend on what mode you are exciting. The highest Q factor would be for the lowest possible mode - water sloshing from side to side could make ten to twenty cycles of visible motion but it would depend upon the depth and all the other dimensions.
 

1. What is the Q factor of a bowl of water?

The Q factor of a bowl of water refers to the quality factor, which is a measure of the damping or energy dissipation in a resonant system. It is a dimensionless parameter that describes how long a system will oscillate after an initial disturbance.

2. How is the Q factor of a bowl of water calculated?

The Q factor of a bowl of water can be calculated by dividing the resonant frequency of the water in the bowl by the bandwidth of the oscillations. This can be determined by measuring the time it takes for the water to stop oscillating after being disturbed.

3. What factors can affect the Q factor of a bowl of water?

The Q factor of a bowl of water can be affected by various factors such as the shape and size of the bowl, the temperature and viscosity of the water, and external forces such as air resistance or friction.

4. Why is the Q factor of a bowl of water important?

The Q factor of a bowl of water is important because it can provide information about the properties and behavior of the water, such as its viscosity and the amount of energy dissipated during oscillation. It is also a useful parameter in engineering and design applications involving resonant systems.

5. How can the Q factor of a bowl of water be increased?

The Q factor of a bowl of water can be increased by reducing the damping in the system, which can be achieved by minimizing external forces and optimizing the shape and size of the bowl. This can result in longer and more sustained oscillations, thus increasing the Q factor.
