In volute casing area of flow increase so due to this decreases in the velocity
and when velocity decreases,the pressure of the water flowing through in the casing increases

Answer / ab_ina7

volute casing is generally spiral in shape with increasing cross-sectional area..when water flows through this then according to continuity equation its velocity decreases resulting in decrease in its kinetic energy...now according to bernoulli's theorem total energy during the flow remains constant, so when kinetic energy decreases then pressure energy and potential energy increases....but increase in potential energy is negligiible

Answer / karthick

the volute casing is nothing but a diffuser.the function of
diffuser is to convert kinetic energy to pressure energy
just opposite to nozzle.so finally we get high 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.

Metals, in general are of low strength and do not possess required physio-chemical and technological properties for a definite purpose. Alloys are therefore more than metals alone. Discuss the arrangement of atoms and structures of alloys.
