<br />As one progresses toward the pump each succeeding length and diameter of
<br />pipe with its friction loss is recorded. The total head loss plus 20 psi
<br />for operating pressure cannot exceed the 73 feet of head present at the
<br />pump. A second or third calculation of head loss is usually required to
<br />come up with the most economical length and diameter of pipe. It is
<br />well to also balance head lasses on either side of a "T" distribution
<br />so as to balance the amount of water going to either side.
