LINE CALCULATION

This is the main equation :

Error must be less 1% of

Solve by iteration :

	This is the variation of volume by pressure , this expresion is converter into		where
	if state is gas then
	if state is liquid then

	This is the varation of friction factor by length of pipe.Friction factor is considerate a constant.

This is the varation of velocity by velocity. gc and alpha is considerated constants.

This is the variation of gravity by grabity, this expresion is a constant.

=

This expresion is considerated zero.
