These charts are obtained from the homogeneous flow model including the effect of gravitational force. PLEASE ALLOW ONE WEEK FOR SHIPMENT. The two diagrams are used as follows: for given inlet pressure and subcooling level/vapour quality, the mass flow rate for the reference capillary tube can be estimated from Figure 2; then, for a given geometry, the flow rate correction is obtained from Figure 3. These newly developed selection charts can be practically used to select capillary tube size from the flow rate and flow condition or to determine mass flow rate directly from a given capillary tube size and flow condition.
