A discharge of 0.15 cumecs is supplied into a canal at the head and 0.1 cumecs is delivered to field having an area of 1.5 hac. The Irrigation is started at a moisture extraction level of 60% of the available moisture and then extends for 10 hours.

The peak discharge for a circular culvert was found to be 1.25 m^3/s. It has been determined that a water flow speed of 1.5 m/s is needed to maintain scour velocity. Calculate the approximate diameter of a circular culvert needed to carry the 1.25 m^3/s if the culvert is flowing at a depth 3/4 of the diameter. Assume that the flow in the culvert is not complex and water does not pond at either end of the culvert.
