OKSY Interview Questions and Answers
Q1. 4. What is polimerization and heat of reaction for polymerization reaction, exo or endo.
Polymerization is a process of combining monomers to form a polymer. Heat of reaction can be exothermic or endothermic depending on the type of polymerization.
Polymerization is a chemical reaction that involves the combination of monomers to form a polymer.
The heat of reaction for polymerization can be exothermic or endothermic depending on the type of reaction.
Exothermic reactions release heat while endothermic reactions absorb heat.

Q2. 7. How to increase the effectiveness of a double pipe heat exchanger.
To increase effectiveness of double pipe heat exchanger, increase surface area, improve fluid flow, and use appropriate materials.
Increase surface area by using longer pipes or adding fins
Improve fluid flow by increasing velocity or using baffles
Use appropriate materials with high thermal conductivity
Consider counter-current flow for maximum heat transfer
Regular maintenance to prevent fouling and scaling
Optimize temperature and flow rate for specific application
Q3. 8. What is mach number and it's significance.
Mach number is the ratio of an object's speed to the speed of sound in the surrounding medium.
It is named after Austrian physicist Ernst Mach.
It is used to describe the speed of an object in relation to the speed of sound.
Mach 1 is the speed of sound, so anything traveling at Mach 1 is traveling at the speed of sound.
Supersonic aircraft have a Mach number greater than 1.
Hypersonic aircraft have a Mach number greater than 5.
Mach number is important in aerodynamics and the desi...read more

Q5. 5.what is murfree efficiency
Murfree efficiency is a measure of the efficiency of a heat engine.
It is a measure of the ratio of the actual work output to the maximum possible work output.
It is named after American physicist and engineer William Henry Murfree.
It is commonly used in thermodynamics and engineering.
It is calculated using the formula: Murfree efficiency = (actual work output / maximum possible work output) * 100%
Q6. 1. Favorite subjects.
My favorite subjects are biology and chemistry.
I enjoy learning about the intricacies of living organisms and their functions.
Chemistry fascinates me because it explains the composition and behavior of matter.
I also appreciate the practical applications of both subjects in fields such as medicine and environmental science.
