Abstract

Optimum size of fillets at the corners of a rectangular duct or a rectangular open channel carrying water to minimize the hydraulic head loss has been worked out. For all the cases viz. a rectangular open channel or a rectangular duct running full or not running full, the optimum size has been found to be 0.24R where R is the hydraulic mean radius.
