*Dear Readers, Welcome to Fluid Mechanics Interview Questions have been designed specially to get you acquainted with the nature of questions you may encounter during your Job interview for the subject of Fluid Mechanics. These Fluid Mechanics Questions are very important for campus placement test and job interviews. As per my experience good interviewers hardly plan to ask any particular questions during your Job interview and these model questions are asked in the online technical test and interview of many IT companies.*

Are you a graduate with mechanical, civil or chemical engineering? Are you passionate to work in laboratory and research field then log on to www. Fluid Mechanics is the branch of science that deals with behavior of fluids gases or liquids and forces on them. Fluid mechanics consists of fluid statics, fluid kinematics, fluid dynamics. Fluid Statics is the study of fluids in rest. Fluid Kinematics is study of fluids in motion considering the pressure force. Fluid dynamics is the study of fluids in motion considering the pressure force.

Why the Centrifugal Pump is called High Discharge pump? Centrifugal pump is a kinetic device. The centrifugal pump uses the centrifugal force to push out the fluid. So the liquid entering the pump receives kinetic energy from the rotating impeller. The centrifugal action of the impeller accelerates the liquid to a high velocity, transferring mechanical rotational energy to the liquid. So it discharges the liquid in high rate.

*Даже в полуметре от шефа она не видела очертаний его фигуры. Всякий раз, ступая на очередную ступеньку, она носком туфли первым делом старалась нащупать ее край.*

И вдруг Сьюзан увидела, что кнопка вызова вовсе не мертва, а просто покрыта слоем черной сажи. Она вдруг начала светиться под кончиком пальца. Электричество. Окрыленная надеждой, Сьюзан нажала на кнопку. И опять за дверью что-то как будто включилось.

* Понятия не имею. Я уже говорила, что мы ушли до их прибытия.*

Фонтейн погрузился в раздумья. Джабба терпеливо ждал, наконец не выдержал и крикнул ассистентке: - Соши. Немедленно. Соши побежала к своему терминалу. Джабба нередко прибегал к ВР, что в компьютерных кругах означало виртуальная реальность, но в АНБ это сокращение имело несколько иной смысл - визуальная репрезентация.

*Забыла. - Там проблема с электричеством. - Я не электрик.*
