SpletExample: For a 2 foot Parshall flume, the discharge equation for a flow rate in GPM, and head in feet, is GPM = 3590 * H^1.55. Since head is already in feet, we only need to convert GPM to CFS. 1 CFS = 448.8 GPM, so dividing by 448.8 give us CFS = 8.0 * H^1.55. This is the equation we would enter into the OCF 6.1 for this flume.
