In fluid mechanics, the letter k is used to represent the coefficient of kinetic viscosity. This is a measure of a fluid’s resistance to flow and is used to calculate the amount of energy required to move the fluid.

### Q: What is K-factor in fluid flow?

A: The K-factor is a dimensionless number that is used to describe the shape of a fluid flow profile. It is used to characterise the cross-sectional shape of a fluid flow, and is defined as the ratio of the width of the flow to its depth.

### Q: How do you calculate K in fluid?

A: K in fluid can be calculated using the following equation:

K = ρg/μ

where ρ is the fluid’s density, g is the acceleration due to gravity, and μ is the fluid’s viscosity.

### Q: What is K in head loss?

A: The value of K in head loss is a function of the fluid’s properties (viscosity, density, etc.), the piping system’s dimensions (diameter, length, etc.), and the flow rate.

### Q: What is resistance coefficient k?

A: The resistance coefficient k is a measure of how much resistance an object has to being pushed through a fluid. The higher the value of k, the greater the resistance.
