Q1. How Vacuum column work?
Ans. 
Vacuum column is used in distillation process to separate different components based on their boiling points.
• Vacuum column operates under reduced pressure to lower the boiling points of the components being separated.

• The column is packed with trays or structured packing to increase the surface area for vapor-liquid contact.

• The feed enters at the bottom of the column and is heated to its boiling point.

• The vapor rises up...read more

Q2. What is Octane number?
Ans. 
Octane number is a measure of a fuel's ability to resist knocking or detonation.
• Octane number is the percentage of iso-octane in a mixture of iso-octane and n-heptane that has the same knocking characteristics as the fuel being tested.

• Higher octane number means the fuel has better resistance to knocking.

• Octane number is important for high-performance engines that require high compression ratios.

• Octane number is determi...read more

Q1. What is Entropy and what is the unit of Entropy?
Ans. 
Entropy is a measure of disorder or randomness in a system. Its unit is joules per kelvin (J/K).
• Entropy quantifies the number of possible microstates in a system

• It is a measure of the system's energy dispersal or the degree of randomness

• Entropy increases with an increase in disorder or randomness

• The unit of entropy is joules per kelvin (J/K)

• Entropy can be calculated using statistical mechanics or thermodynamics

• Example:...read more

Q2. Which engine is best 2 strokes or 4 strokes?
Ans. 
Both engines have their own advantages and disadvantages depending on the application.
• 2-stroke engines are lighter and have higher power-to-weight ratio, making them ideal for small applications like chainsaws and mopeds.

• 4-stroke engines are more fuel-efficient and have a longer lifespan, making them ideal for larger applications like cars and boats.

• Environmental concerns have led to a decline in the use of 2-stroke en...read more
