BARC Interview questions


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?
  •  Explain shear force and bending moment diagram of
    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.
  • Design of shafts is not based on Shear forces. Why?
  • Where to place a pump along vertical head line ?
  •  Log. profile in heat exchanger? concave or
    Convex?
  • While inflating a balloon P and V both are increasing.
    Violets Boile’ s law. Explain.
  • Explain True and Engineering strain.
  • Stress-strain diagram. Very detailed knowledge reqd.
  •   Shear profile in a cross section of a beam.
  •  In pelton wheel turbine cup, both outward and
    inward speed are equal. explain.
  •  Cavitations, Water Hammer. Explain.

    conceptual papers).
  •  Design of air duct.
  •  Charles law , Boyle’s law.
  •  If 2 cylinders connected by a pipe to allow the
    gases to diffuse, then draw the PV and TS diagrams of process.
  • Why we opt PV in some cases while TS diagrams in
    others?
