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
