Three feet of flash boards were placed on the top of a small diversion dam. The pipes holding the boards were placed 10 ft apart across the dam. There were 20 pipes and each one was designed to fail under a bending moment of 1625 ft-lb how deep will the water be on the flash boards when failure occurs? Assume hydrostatic pressure distribution on the flash boards.
