thanks for that. yeah i had 3 90 degrees in mind. and that was not the question.sure u can have 2 right angles anywhere. thanks.

i don't know how u'd reach the same point without reaching the equator. Then it should be possible to draw a triangle with angles 90 degrees with side of any dimension on any part of the sphere. i don't think so...

it goes like this. we all know that there r no bears in the southpole. now consider the middle of the north pole, go straight and u will reach the equator, then take a 90 degree turn east and through the equator walk the same distance, now take another 90 degree north and walk the same...

Thanks for the suggession. but there was a change of consideration. I realize that the rate we will deal with is too small for any accurate measurements. A loss of a few drops may make huge errors. So i have decided to change the membrane pore size to increase it to something like 1ml/sec...

Sorry for the late reply.I am giving u more information on this. This will be a closed tube. But the purpose of the experiment is to study convection at high rayleigh no: at the limit of large prandtl no:...but this will primarily be concentration driven convection from a lower tank through a...

hey, Can anybody suggest a method of measuring very small flow rates of a few ml per hour precisely.This is a diffusion experiment where water is allowed to pass through a membrane at a constant pressure.we have to know the amount of water passing through the membrane.There will not be any...

diffusion through a membrane hey, can u suggest some simple methods of measuring fluid flow rates of a few ml per hour when a lighter/low viscous fluid is allowed to pass through a membrane a certain pressure?
