Abstract
The flow at the entrance to the two-way drop inlet is analyzed theoretically and an expression for the loss coefficient at the crest is developed. It is assumed that a jet forms in the drop inlet and that the crest head loss is a result of the expansion of this jet. The theoretical loss is a simple function of the jet width. This width can be determined by free streamline potential flow methods. The theoretical crest loss coefficients compare well with experimental values.
