EXAMPLE , PART II

Example I :

The following results come from computation with a two components flow (air-water) in a  89.9 meters lenght horizontal pipe .
Pipe diameter is constant equal to 5.3 cm .
Components velocities : U(gas) = 3.75 m/s
U(liquid) = 1.0 m/s
The flow temperature is constant in the pipe, equal to 20 degrees C (293 K) .
