Bonfiglioli Transmissions Private Limited Design Engineer Interview Questions and Answers

Q1. What is mean by kinetic energy
Ans. 
Kinetic energy is the energy possessed by an object due to its motion.
• Kinetic energy is directly proportional to the mass of an object and the square of its velocity.

• The formula for kinetic energy is KE = 0.5 * m * v^2, where m is the mass of the object and v is its velocity.

• Examples of kinetic energy include a moving car, a swinging pendulum, or a flying bird.

Q2. What is the slip angle in Impeller
Ans. 
Slip angle in impeller refers to the angle between the direction of fluid flow and the blade angle.
• Slip angle is an important parameter in impeller design as it affects the performance of the pump.

• It is generally kept small to minimize energy losses due to fluid slip.

• Slip angle can be calculated using computational fluid dynamics (CFD) simulations.

• For example, a slip angle of 5-10 degrees is common in centrifugal pumps
