It has been an usual practice, in calculating the water-circulation in boilers, to assume that the boiler tubes are uniformly heated along their length and that the relative velocity between vapour and liquid is either constant or neglisgible. These assumptions, however, are far from reality. In this paper, is presented a method of calculation without these assumptions. An accompanied nomogram makes the process of calculation even simpler than the processes by usual methods. The relative velocity is discussed on the basis of the experiments hitherto published, and is expressed in a general form so that the necessary coefficients for each particular case can easily be found.
