CONT

Critical lip pressure method... If hot water or a water/steam mixture is discharged at sonic velocity through an open-ended pipe, and if the pressure is measured at the discharge lip of the pipe, this pressure is a measure of the heat flow of the discharged fluid.

PHR

Critical lip pressure.

PHR

Lip pressure method.

CONT

Méthode de la pression critique de bordure. Si de l'eau chaude ou un mélange eau/vapeur est dégagé à la vitesse du son à travers un tuyau à extrémité dépourvue de filetage, et si la pression est mesurée à la bordure du dégagement du tuyau, cette pression est une mesure du flux de chaleur du fluide dégagé.

PHR

Pression critique de bordure.

CONT

Critical lip pressure method... If hot water or a water/steam mixture is discharged at sonic velocity through an open-ended pipe, and if the pressure is measured at the discharge lip of the pipe, this pressure is a measure of the heat flow of the discharged fluid. James has deduced... [a] formula expressed in f. p. s. units... Where the two phases of a water/steam mixture are segregated by means of a cyclone separator the water can be measured either by a cooled orifice or, after allowing for the flashed steam, by means of a V-notch or weir. Alternatively, however, the water may simply be discharged at sonic velocity through an open-ended pipe and measured by applying... [James] formula. By measuring the temperature of the water leaving the separator its enthalpy is made known, and... [the flow] can be deduced from... [the critical lip pressure].
