- Q2. Tube pitch of shell and tube heat exchanger?
- Ans.
Tube pitch is the distance between the center of two adjacent tubes in a shell and tube heat exchanger.
Tube pitch affects the heat transfer rate and pressure drop in the heat exchanger.
It is typically between 1.25 and 2 times the outside diameter of the tubes.
A larger tube pitch can reduce fouling and make cleaning easier, but may require more tubes and increase the size of the heat exchanger.
The tube pitch should be o...

- Q1. Chemical Engineers are generally placed in Water, Environment, Chemical or Power discussion.
- Q2. What is distillation
- Ans.
Distillation is a process of separating components of a mixture based on their boiling points.
It involves heating the mixture to vaporize the more volatile component
The vapor is then condensed and collected as a separate liquid
Commonly used in the production of alcoholic beverages, fuels, and chemicals
- Q3. Application of distillation
- Ans.
Distillation is a process used to separate components of a mixture based on their boiling points.
Used in petroleum refining to separate crude oil into different fractions
Used in the production of alcoholic beverages to separate ethanol from water
Used in the chemical industry to purify solvents and separate different chemicals
Can be used in the purification of water
Can be used in the separation of air into its component
- Q4. Type of heat exchangers
- Ans.
Heat exchangers are devices used to transfer heat between two or more fluids.
Shell and tube heat exchangers
Plate heat exchangers
Double pipe heat exchangers
Spiral heat exchangers
Air-cooled heat exchangers
- Q5. Bubble point vs dew point
- Ans.
Bubble point and dew point are two important concepts in thermodynamics used to describe the behavior of a mixture of liquids and gases.
Bubble point is the temperature at which a liquid mixture starts to boil and form bubbles of vapor.
Dew point is the temperature at which a vapor mixture starts to condense and form droplets of liquid.
Bubble point and dew point are related to each other through the vapor-liquid equilibr...
- Q6. Chemical vs Biological oxygen demand in Water chemistry
- Ans.
Chemical and Biological Oxygen Demand are measures of water quality and indicate the amount of oxygen required to break down organic matter.
Chemical Oxygen Demand (COD) measures the amount of oxygen required to oxidize organic and inorganic matter in water.
Biological Oxygen Demand (BOD) measures the amount of oxygen required by microorganisms to break down organic matter in water.
COD is a faster test and measures both ...
