Dearest friends...

I actualy would like to enter in contact with yourselves since 23 th March 2003 for some discussions. But unfortunately I couldn't because I was so busy and my internet-computer system was out of order.

But now here we go....

From the International Critical Tables, the viscosity of water at 20 deg C is 0.010 08 poises. How to find that value, if in undeveloped country like East Timor there are no Laboratory for this purposes, because I use to discuss with some of my colleagues that we have to know the correct tempertaure of water in Deg Celsius to find the correct viscosity of water in order to facilitate us for some calculation of Presure Head and other porpuses. Could furthermore you tell me the other purposes of water viscosity? For your attention I tank you very much and see you in next time............
