Abstract
One of the most economical and simple methods of determination of two-phase flow parameters in geothermal well testing is the so-called James' method [ 1,2 ]. The method consists of the measurements of lip pressure (p), and the flow rate of water (w) by a conventional weir. The stagnation enthalpy (h ) is then determined from a plot showing versus which is &npirically determined by James [ 1, 2 ]. The mass flow rate is then determined from the following empirical formula: Formula follows (see pdf).
