Bernoulli theorem explains the relationship between fluid velocity, pressure, and elevation.

• Bernoulli theorem states that as the velocity of a fluid increases, its pressure decreases.

• It is based on the principle of conservation of energy in fluid flow.

• The theorem is commonly used in fluid dynamics and aerodynamics.

• It can be applied to various situations like flow through pipes, airfoils, and nozzles.

• For example, when w...read more

AC and DC are two types of electrical current. AC changes direction periodically while DC flows in one direction.

• AC stands for Alternating Current and DC stands for Direct Current.

• AC changes direction periodically, typically at a frequency of 50 or 60 Hz.

• DC flows in one direction continuously.

• AC is used for power transmission over long distances.

• DC is commonly used in batteries and electronic devices.

• AC can be easily c...read more

Six Sigma is a data-driven methodology used to improve business processes by reducing defects and variability.

• Six Sigma aims to achieve a level of quality where the probability of defects is extremely low.

• It uses statistical analysis to identify and eliminate sources of variation in a process.

• The methodology follows a structured approach called DMAIC (Define, Measure, Analyze, Improve, Control).

• Six Sigma is widely used...read more

Fishbone diagram is a visual tool used to identify the possible causes of a problem or an effect.

• Also known as Ishikawa diagram or cause-and-effect diagram

• Consists of a central spine and branches that represent different categories of potential causes

• Used in quality control, process improvement, and problem-solving

• Example: A fishbone diagram can be used to identify the possible causes of defects in a manufacturing proc
