Fluid Dynamic

lately im forcing myself to read the laws realted to fluid dynamic; the charles's law, boyle's lay, mass flow rate , dalton's law to prepare myself better for the job interview. well im not sure what kind of technical test that im going to sit but have to prepare for all the formula and calculation plus the definition of each law. Quite a tough one to read back all the definition but basically i do understand most of it. just need for a quick refreshment for it. ive been study all the terms and formula few years ago but never use it for my job purpose as a Mechanical designer.

I surfed the wikipedia website as a way to refresh my memory about it.

here is what i can found about all the law related to fluid dynamic

1. Charles's Law

charles's law stated that for every increase in temperature will increase the volume of the gas inside the chamber if the pressure of it remain constant.

2. Boyle's law.

Boyle's Law tells us that there is an inversely proportional relationship between the pressure and the volume of gases. and the basic formula would be P x V = K
(k, constant )

3. Mass flow rate.

Mass flow rate is the movement of mass per time. Its unit is mass divided by time, so kilogram per second in SI units, and slug per second or pound per second in US customary units.

it can be calculated thru this formula where
mass flow rate= density x v x A
where v: velocity
A: flow area
4. Dalton's Law

The total pressure of a gas mixture equals the sum of the partial pressures that make up the mixture.

P=p1+p2
where p1= pressure of the A
p2= pressure of the B

and now just do the best and prepare for the worst.
