Vena contracta is the point of minimum area in a fluid stream where the velocity is at its maximum.

• It is the point of maximum velocity in a fluid stream

• It is the point of minimum area in a fluid stream

• It is important in fluid mechanics and is used to calculate flow rate

• It is commonly used in the design of valves and orifices

Bevel angle is the angle formed between the two intersecting surfaces of a bevel.

• It is commonly used in metalworking and woodworking.

• The angle can vary depending on the application and material being worked on.

• A larger bevel angle can result in a stronger joint or edge.

• Bevel angles can be measured using a protractor or angle gauge.

• Examples of beveled edges include the edges of chisels, knives, and saw blades.

The volume of a cylinder is calculated by multiplying the area of the base by the height of the cylinder.

• The formula for calculating the volume of a cylinder is V = πr²h, where r is the radius of the base and h is the height of the cylinder.

• The volume of a cylinder can be used in various engineering and scientific applications, such as calculating the amount of fluid that can be stored in a tank.

• The volume of a cylinde...read more
