Types of Flows in a Pipe

Types of Flows in a Pipe - The type of flow of a liquid depends upon the manner in which the particles unite and move. Though there are many types of flows, yet the following are important :

1. Uniform flow: A flow, in which the liquid particles at all sections of a pipe or channel have  the same velocities, is called a uniform flow.

2. Non-uniform flow: A flow, in which the liquid particles at different sections of a pipe or channel have different velocities, is called a non-uniform flow.

3. Streamline flow: A flow, in which each liquid particle has a definite path and the paths of individual particles do not cross each other, is called a streamline flow.

4. Turbulent flow: A flow, in which each liquid particle does not have a definite path and the paths of individual particles also cross each other, is called a turbulent flow.

5. Steady flow: A flow, in which the quantity of liquid flowing per second is constant, is called a steady flow. A steady flow may be uniform or non - uniform.

6. Unsteady flow: A flow, in which the quantity of liquid flowing per second is not constant, is called an unsteady flow.

7. Compressible flow: A flow, in which the volume of a fluid and its density changes during the flow, is called a compressible flow. All the gases are considered to have compressible flow.

8. Incompressible flow: A flow, in which the volume of a fluid and its density does not change during the flow, is called an incompressible flow. All the liquids are considered to have incompressible flow.

9. Rotational flow: A flow, in which the fluid particles also rotate (i.e. have some angular velocity) about their own axes while flowing, is called a rotational flow.

10. Irrotational flow: A flow, in which the fluid particles do not rotate about their own axes and retain their original orientations, is called an irrotational flow.

11. One-dimensional flow: A flow, in which the streamlines of its moving particles are represented by straight line, is called an one-dimensional flow.

12. Two-dimensional flow: A flow, whose streamlines of its moving particles are represented by a curve, is called a two-dimensional flow.

13. Three - dimensional flow: A flow, whose streamlines are represented in space i.e. along the three mutually perpendicular directions, is called a three - dimensional flow.

Are Engineers Favourite Among Girls?

What do girls think about men who are engineers and what type of engineers are most favourite among girls? A survey was conducted by a team of aboutmech with members chosen from different countries. Each team member carried out a neutral survey in his/ her country to evaluate what females think about most of the engineers from different engineering branches. An overview of different questions asked in survey is given below: Question: Which male engineers do you find more attractive as a husband? Almost 50% women voted for mechanical engineers to be the most attractive husbands among other engineers. So mechanical engineers are most favourite among girls as a husband. They find them more trustworthy, intelligent, and creative. A married women from California said, “If your husband is a mechanical engineer, he will help you in everyday tasks. Because mechanical engineers are good team players and they have creative ideas about everything.” Which male engineers do you find more

Best CV Format for Mechanical Engineers

Fifty percent engineers fail to grab a dream job because of basic faults in their CVs/ Resume. This article tells you about best CV format for mechanical engineers and how you are supposed to design your CV when applying for jobs. You CV is your first impression on future employer. He/ she does not know you. Your CV is the only representation of your personality. He/ she may select or reject you after first glance on your resume.  I have experienced shortlisting and interviewing candidates for different jobs. I was astonished to learn that most of the candidates simply copy paste each others CVs without any changes at all. These types of CVs are rejected immediately. I am not trying to tell you that you should avoid copying, rather i ma telling you to refrain from giving your CV to your friends. An ideal CV consists of following portions: Name/ Address of the applicant Objective Education Record Employment History Professional Skills Awards & Achievements Co-Cu

Engineering Mechanics - Introduction

The Engineering Mechanics is that branch of Engineering-science which deals with the principles of mechanics along with their applications to engineering problems. It is sub-divided into the following two main groups: (a) Statics, and (b) Dynamics The Statics is that branch of Engineering Mechanics which deals with the forces and their effects, while acting upon the bodies at rest. The Dynamics is that branch of Engineering Mechanics which deals with the forces and their effects, while acting upon the bodies in motion. It is further sub-divided into the following two branches: (i) Kinetics, and (ii) Kinematics The Kinetics is that branch of Dynamics, which deals with the bodies in motion due to the application of forces. The Kinematics is that branch of Dynamics which deals with the bodies in motion without taking into account the forces which are responsible for the motion.
