Hi guys, quick simple question. Lets say I have a pipe separated into 3 sectoins (all horizontal), all have the same flow areas. In the first section it is all liquid water. I know the mass flow rate in this. In the second section the water is heated. And I can work out the steam quality here. In the third section there is a mixture of water and vapour. I would like to know the superficial vapour velocity in this section. ------------------------- If I know the quality, that means I know the mass flow rate of vapour, from x = mdot-vapour / mdot-total, right? From mdot-vapour [kg/s], could I multiply it by the specific volume [m3/kg] to get the volumetric flow rate of vapour? If I have the volumetric flow rate of vapour, I should be able to just get the vapour superficial velocity by dividing volumetric flow rate over flow area, right?
