6.1.1 Backward Design

Suppose that we have n sections with n gates. We know that volume to be delivered at gate i and is denoted by . The gate velocity has to be in a known range. The filling time has to be in a known function and we recomend to use Eckert/Bar-Meir's formula. For this discussion it is assumed that the filling has to be in known range and the flow rate can be calculated by

Thus, gate area for the section

Armed with this knowledge, one can start design the runner system.
