Centrifugal pump works by converting mechanical energy into kinetic energy to increase the fluid's velocity and pressure.
The pump has an impeller that rotates to create a centrifugal force.
Fluid enters the pump through the suction nozzle and is directed to the impeller.
The impeller's rotation causes the fluid to move radially outward, increasing its velocity.
The fluid then enters the volute casing, where the velocity i...

Interview Preparation Tips
Experience: Online Aptitude test. I attempted the verbal section firstly, since I was more confident on that part. After I was done with it, I opted for the questions of my domain and lastly the quant. Speed and accuracy were the deciding factors in that test.
Duration: 45 minutes
Total Questions: 45
Round: Group Discussion
Experience: I had chosen to speak for the Sales and I was the first one to counter the person who spoke for R&D. Key was to let other's speak, listen carefully to your counterparts and have a positive body language throughout to make the moderator feel that you are very much a team person as well as you've your own standpoint.
Duration: 20 minutes
Round: Technical Interview
Experience: Technical interview was conducted face to face with 2 interviewers.
Tips: Accept what you don't know but steer the interviewers to your strong points. You have to be clear on your favorite subjects or on the previous internships or trainings done. The person sitting opposite to you will try to puzzle you on your own answers. Try to be very clear on what you say.
Round: HR Interview
Experience: HR interview was over phone call. What I felt as to crack a interview, you don't have to be too clever.
Tips: Don't panic and keep your mind free of any expectations beforehand. That's all about my personal experience. :)

- Ans.
Boiler efficiency can be measured by calculating the heat input vs. heat output.
Calculate the heat input by measuring fuel consumption and its calorific value.
Calculate the heat output by measuring steam flow rate and its temperature.
Divide the heat output by the heat input and multiply by 100 to get the efficiency percentage.
Regular maintenance and tuning can improve boiler efficiency.
