The Simple Pleasures in Our Lives

While some are singing poetically, lemme add in sth too, erm... in a more technical aspect... hee hee~ not abt spring though... erm... just another random thought... hee hee~

Here's an interesting question:
How would you determine the rate of flow of water from a pipe, ie, volume of water passing through a point per sec?

Possibility A: A Mathematician will first find the velocity vector v of the water flow, and also the change in time t(which is 1 sec) and multiply them together to get the displacement. Then measure the cross sectional area A of the pipe and multiply it with the displacement and doing some triple integrals here and there to get the volume of the water flowing thru a point per sec.
*hmmm, sounds logical... of cuz it works! It's being taught in the university!!! Though College education all tok kok one la... all only on paper... but den it should work... sounds good!*

Here's Possibility B (an add-on to A): A Physicist will think that the Mathematician is being too inaccurate because Mathematicians like to neglect stuff here and there... He feels that the turbulance of the water and the friction between the pipe walls and the water molecules should be taken into considerations too, along with some other funny resistance... After referring to and using the various formulas from the Fluids Chapter of the Physics textbook, he comes up with an even more accurate answer to the fluid flow rate problem. *Hooray!*

Well, here's Possibility C (by Tian Cai): THE Tian Cai will bring the pipe over a container used to measure volume and allow all the water from the pipe to flow into (Without spillage) it for a span of 60 sec. After that he uses mental calculations to divide the measured volume by 60 and Lo and Behold! you get the flow rate too! by using V/60 :)

Yeah! The tian cai does it again! Hip Hip...!!! =)
