I'm not going to look at the archaic maths, but it does not seem
to have taken into account the function of a water pipe. Its
purpose is not to store water, but to allow its movement.
"Movement" may be interpreted as a constant supply of water at a
likely minimum of about 140 (gasp!)F. <br>

I'm amazed this is even a matter of discussion, particularly with
most participants in North America. If there really is any query
about certification, all will be revealed in section 8 of <br>
