The watershed at a particular site on a river has 77000 ha. The mean annual precipitation is 950 mm. About 25% of precipitation reaches the basin outlet as stream flow. Estimate the mean flow rate Q at this site in m³s-1. If the head available at the site is 150 m and assuming the transmission loss of 10%, what would be the power that can be generated in MW?
