Answer Posted / shashi prakash singh
the basic difference lies on the energy that they employ to
do work in the impulse turbine,wherein the change in
velocity(change in steams' direction)due to curvature of
the blades results in drop of the kinetic energy thereby
doing the useful work[IMPULSIVE ONLY]
while in a reaction turbine the converging crossection of
the blades results in the increase of the kinetic energy at
the expense of its pressure energy and this energies
together employ doing the work[IMPUSIVE AS WELL AS THE
PRESSURE]

Hello there, Im a Mechanical Engineer. I passed out in 2010 and have worked for 6 months in the Middle East as a Trainee Engineer. Im now in India and due to appear for an Interview for a firm in the Middle East. The post is of an Automobile Engineer. Im kinda nervous as to what to prepare for the interview. The training which I got was in different areas ranging from technical to managerial aspects. What I mean to say is that that was more of a crash training, where I couldn't stick to one section alone. The interview which Im attending is more of a technical one. What I would like to know, how and what I should be preparing? I have two weeks for the preparation. Should I go through the normal automobile aspects or everything in random. PS: I have excellent communication skills, the one area in which I'm very confident.
