Saturated water enters a pipe of 1 m length, the first 0.25 m of which are unheated. Heat is supplied to the remainder of the pipe at a fixed rate (see group 13 below). The processes considered are:- * heat transfer from the wall to the liquid; * heat transfer from the liquid to the steam-water interface; * mass transfer across the interface, at a rate determined by the heat balance; * heat transfer between the interface and the bulk of the steam; * momentum transfer (friction) between the water and the steam; * pressure-gradient and inertia effects on the water and the steam. The task is to calculate the steady-state distributions along the pipe of pressure, volume fractions, enthalpies, and velocities.
