WebThe conduit may flow completely full (pressure flow) or partly full (free surface flow). The free surface flow may be supercritical or subcritical depending on tailwater conditions. When critical depth is lower than uniform depth, the slope is termed mild. Pressure flow or free surface flow may occur. Webcritical flow occurs for the minimum specific energy; at critical flow conditions the Froude number is unity; (b) at a control section critical flow conditions take place and this fixes a unique relationship between depth and discharge in the vicinity (e.g. sluice gate and weir); (c) county check with zip codes https://fierytech.net
