Why overall efficiency of thermal power plant is very low?

The major part of the electricity that world is producing nowadays comes from Thermal Power Plant (which works on Rankine Cycle or Modified Rankine Cycle).

The principal parts of the Thermal Power Plants are

  • Boiler (to generate steam from water)
  • Turbine (where the steam expands and produces the work in form of rotation of shaft which in turn rotate the generator)
  • Condenser (where major part of heat is rejected to convert steam into water for reuse)
  • Feed Pump (to pump back the feed water to boiler for steam conversion) 
All parts except the condenser have 80 % to 90 % efficiency. The only condenser has 50% efficiency. 
Thus overall efficiency comes down to 30 % - 40 %

How to write an abstract for technical report or article or paper?

An Abstract is an important element of any technical report or any research paper/article. It is something which people normally prefer to read before taking a look at the whole article. The abstract must contain the enough information which highlights and give the complete essence of the article. 

Normally abstract should deliver objectives of the research, methods that one has used for research, key results obtained and a clear and concise conclusion. 

The abstract should contain minimum 100 to 200 words. The content of the abstract should be clear and concise. 

It should highlight the main objectives and motivation of the research. Do not write an equation and related stuff in it. 

Avoid putting references in an abstract. One should not use in this 'paper' or 'article' but use 'research' or 'investigation'. 

The abstract must have enough information which develops the interest to read the full paper or article.


Tips for GPSC Interview for lecturer and assistant professor

These are the tips which can be helpful to clear the GSPC personal interview for lecturer and assistant professor
  1. Have confidence in your answer while you are asked to speak about yourself. This is normally very first question asked by chairman of interview "Tell me about yourself". Make answer ready in advance. Speak your full name, age, qualification with college and university,current job.
  2. Now when you are asked about your job, give positive aspects of job.
  3. Why do you want to do teaching job? Why not current job? Do not say I am not enjoying the current job but say, "I love teaching and this changes lives of people. I want to impact the life of many by teaching job. This job is respectful job"
  4. Always ready with two or three favorite subjects. 
  5. Prepare DEMO lecture that will be most probably asked to deliver. 
  6. SAY "NO" IF YOU ARE NOT VERY SURE ABOUT QUESTION'S ANSWER. IF YOU GIVE WRONG ANSWER THEY WILL TRAP YOU AND ULTIMATELY TIME AND YOUR REPUTATION WILL BE WASTED. Just say 'No' and pass the question. New question might be familiar to you. This will have impact of honesty on interviewer. 
  7. DO NOT ARGUE. DO not hurt them by saying I AM right even though they are wrong. They just make sure about your character. 

List of different seminar topics in mechanical engineering - Cryogenics

Followings are the different seminar topics in mechanical engineering which are mainly related to cryogenics. Cryogenics is a branch of science/engineering which deals with production of very low temperature below -150 degree C ( or 123 K). These topics are associated with production, storage and maitenance related to cryogenics engineering.

  • Cryogenics insulation
  • Vacuum as cryogenics insulation
  • Liquefaction of permanent gases
  • Applications of cryogenics
  • Medical application of cryogenics
  • Physics applications of cryogenic
  • Space applications of cryogenics
  • Cryocoolers and its types
  • Stirling cryocoolers
  • GM cryocooler
  • Pulse tube cryocoolers
  • Instrumentation and Measurement in cryogenics
  • Storage and transportation in cryogenics
To start with any of the above seminar topic, one need to first give its introduction, methodology or description and construction, working procedure, observation or specifications of different parameters and applications if any.
