(This blog post has the potential to be discursive and go in no particular direction, so I'll try my best to remain as unwavering as I can)
It all started off when our washing machine konked off and decided to stop working. My grandma sent it off to the repairers who fixed it and then had the brilliant idea to suggest attaching a water pump so that water from the tank above would flow in much faster. Now, anyone who has played with a syringe would know that no matter how hard you push (or pull), you just can NOT for the love of anything (or anyone) get more than a certain amount of liquid through the syringe (or in this case the pipe).
Now, our pipes are really old and are rusting from the inside. This is the reason that the flow of water has gone down as compared to the time when they were first installed. Even though I suggested getting the pipes changed due to the above mentioned reason (since that is the real problem, my grandma would hear nothing from me... Oh well... so be it...)
The brilliant engineer's suggestion came as a massive shock to me and it almost felt funny. Anyways, the pump has been installed and guess what... The flow of water in the pipe is still the same!! I wonder how that happened. Isn't the pump working (scratch head, etc...)
The rate of flow of water in a pipe depends upon many things. One of them being the inner diameter of the pipe and another being the friction offered by the sides of the pipe. I don't know the exactly formula, but I am guessing it is easy to come by. The pressure exerted by the water in the tank is more than sufficient to max. out the flow rate in the pipe and I would have guessed those engineers to know that. I guess it's back to the drawing board for them ;)
