  • Q1. What is prandtl number?
  • Ans. 

    Prandtl number is a dimensionless number used in fluid mechanics to describe the ratio of momentum diffusivity to thermal diffusivity.

    • It is named after the German physicist Ludwig Prandtl.

    • It is used to predict fluid flow behavior and heat transfer in different materials.

    • It is calculated as the ratio of kinematic viscosity to thermal diffusivity.

    • It is important in the study of boundary layers, turbulence, and convection...

  • Q2. Why are manholes circular?
  • Ans. 

    Manholes are circular because they cannot fall through their own opening.

    • Circular manholes cannot fall through their own opening, unlike square or rectangular ones.

    • Circular shape distributes weight evenly, making it easier to move and handle.

    • Circular shape also reduces the risk of injury from sharp corners.

    • Circular manholes are easier to manufacture and install.

    • Circular shape allows for easier access from any angle.

  • Q3. Explain bernoulli's equation
  • Ans. 

    Bernoulli's equation relates the pressure, velocity, and height of a fluid in motion.

    • Bernoulli's equation is based on the principle of conservation of energy.

    • It is commonly used in fluid mechanics to analyze the flow of fluids through pipes and channels.

    • The equation states that as the velocity of a fluid increases, its pressure decreases, and vice versa.

    • It can be expressed as P + 1/2ρv^2 + ρgh = constant, where P is pr...
