Q1. How to design the diameter of distillation column
Ans. 
The diameter of a distillation column is designed based on factors such as feed flow rate, composition, pressure, and efficiency.
• Calculate the required vapor and liquid flow rates based on the feed composition and desired separation efficiency.

• Consider the pressure drop along the column and the desired residence time for the vapor and liquid phases.

• Use design equations and correlations to determine the optimal diameter...read more

Q2. How to calculate no of trays and reflux ratio?
Ans. 
Number of trays and reflux ratio can be calculated using various methods such as McCabe-Thiele method or Fenske equation.
• Use McCabe-Thiele method for distillation columns to determine number of trays required.

• Calculate reflux ratio by dividing the liquid returning to the column by the liquid leaving the top tray.

• Consider factors such as desired separation efficiency and operating conditions when determining number of t

Q4. How to calculate p drop in a pipe
Ans. 
To calculate pressure drop in a pipe, use the Darcy-Weisbach equation or the Hazen-Williams equation.
• Use the Darcy-Weisbach equation: ΔP = f * (L/D) * (ρ * V^2) / 2

• Use the Hazen-Williams equation: ΔP = 10.67 * Q^1.85 / (C^1.85 * D^4.87)

• Where ΔP is the pressure drop, f is the Darcy friction factor, L is the pipe length, D is the pipe diameter, ρ is the fluid density, V is the fluid velocity, Q is the flow rate, and C is...read more

Q5. Explain le chatelier principle
Ans. 
Le Chatelier's principle states that a system at equilibrium will respond to a stress by shifting to counteract the stress and restore equilibrium.
• If a stress is applied to a system at equilibrium, the system will adjust to minimize the effect of the stress.

• Changes in concentration, pressure, or temperature can cause a shift in equilibrium.

• For example, if more reactants are added to a system at equilibrium, the system ...read more
