### Equation of Continuity

If an incompressible liquid is continuously flowing through a pipe or a channel (whose cross sectional area may or may not be constant), the quantity of liquid passing per second is the same at all sections. This is known as equation of continuity of a liquid flow. Mathematically,

Q1 = Q2 = Q3 = .....

or

a1v1 = a2v2 = a3v3 = .....

### 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
