# 30+ Previous Years BARC OGES interview Questions for Mechanical

In month Jan-feb of Every year Bhabha Atomic Research Centre (BARC) is conducted the written test for recruiting the young talented engineers for their Trainee Research Program. written test followed by High voltage Interview. They asked some highly conceptual questions in interview. so in order to make your preparation easy

Here We are posting some Previous year Interview Questions. Many of students who is going to appear in the Interview can get general Idea from these questions.

## BARC PREVIOUS YEAR INTERVIEW QUESTIONS

1. Draw Rankine Cycle and give its physical significance of every point.

2. Why not we feed the steam from turbine to boiler? If lower line brought to y=0 then what is the efficiency and physical situation?

3. Pascal’s law and Pascal Paradox?

5. Heat transfer between slabs having temp. gradient, temperature profile. Find thermal conductivity K.
