Determine the flow regime for upward flow of 10 Kg/s of R-11 in a vertical 0.1 m diameter tube at 10 bar and 25% quality. For a horizontal miniature tube of 1 mm inner diameter, determine the flow regime for 1.5x10-3 kg/s of water-steam at 1 atm and 10% quality. For a horizontal circular tube with an inner diameter of 5 cm (D-0.05 m), determine the flow regime for 1.5x10-3 kg/s of steam-water flow at 1 atm and 59% quality. The flow of 0.1 kg/s of air and 5 kg/s of water at 20 °C and 1 atm at a given point in a horizontal channel is in the bubbly regime. Describe qualitatively how the two-phase flow should change to achieve stratified flow.

ANSWER To determine the flow regime for each problem we need to calculate the Froude number which is defined as the ratio of the inertial force to the gravitational force The Froude number is calculat... View the full answer
