**BARC Interview questions:-**

- Draw Rankine Cycle and give its physical significance

of every point. - 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? - Pascal’s law and Pascal Paradox?

all possible cases of loading - Heat transfer between slabs having temp.

gradient, temperature profile. Find thermal conductivity K. Find same

thing for a cylinder case. modification of temp. profile for both cases

when there is heat generation too involved. - Details on Thermal conductivity K , and Convection Coefficient h.
- Modes of Heat transfer? Which is 4th one.
