The fluid flow resistance through the round tube in boiling is different from the two-phase flow, but it is not very identified.
It has been definitely shown that as the result of semi theoretical analysis and experiments in net boiling of forced flow in 20∅ tube at 3 to 13m/sec, 2 to 150 ata and in 14×10⁵kcal/m²hr, the turbulency of flow by turbulent energy based upon the detach from the tube wall and growth of the bubbles is generated, and the fluid flow resistance is also changed. But this turbulency is not larger than the turbulency of normal flow in tube except cases of low flow velocity or low pressure, and that effect is neglisible in practice. Then the coefficient of frictional flow resistance through the round rough tube in normal turbulent flow is available to in heigh velocity flow at heigh pressure in net boiling too.
