Q1. What is Bayer process
Ans. 
The Bayer process is a method for refining bauxite into alumina, which is the precursor to aluminum production.
• The Bayer process involves crushing and grinding bauxite ore, then mixing it with sodium hydroxide at high temperatures to dissolve the alumina content.

• The resulting solution is filtered to remove impurities, then cooled and seeded to promote the precipitation of pure alumina hydrate.

• The alumina hydrate is the...read more

Q2. What, according to you, most important dimensionless number and why
Ans. 
The most important dimensionless number is the Reynolds number, as it determines the flow regime of a fluid and is crucial in fluid dynamics.
• Reynolds number is used to predict flow patterns in different fluid flow situations

• It is defined as the ratio of inertial forces to viscous forces in a fluid flow

• Reynolds number helps in determining whether the flow is laminar, turbulent, or transitional

• It is widely used in engine...read more

Q3. One equation that correlates HT and Fluid flow
Ans. 
The equation that correlates HT and fluid flow is the Darcy-Weisbach equation.
• The Darcy-Weisbach equation relates the head loss due to friction in a pipe to the velocity and diameter of the pipe, as well as the friction factor.

• It is commonly used in fluid mechanics and hydraulic engineering to calculate pressure drop in pipes.

• The equation is expressed as: hL = f * (L/D) * (V^2/2g), where hL is the head loss, f is the f...read more

Q5. What is dry steam and wet steam
Ans. 
Dry steam has low moisture content and high temperature, while wet steam has high moisture content and lower temperature.
• Dry steam is produced when water is heated to its boiling point and vaporizes without any liquid water droplets present.

• Wet steam contains water droplets suspended in the steam, resulting in a lower temperature compared to dry steam.

• Dry steam is commonly used in steam turbines for power generation, w...read more
