A rectangular channel 6 m wide by 1 m deep is lain on a slope of 0.001 and has a roughnes coefficient of 0.013. What is the mean velocity of flow (m/s) when the canal is full? What is the minimum capacity of the channel in m3/s?

Q13: A sharp crested weir of Im height is fixed across 5m wide channel as shown in the following figure. The depth of flow on the upstream and downstream sides of the weir is 1.5m and 1.2m respectively. Find the discharge over the weir. y=15m H Water level W-1 m HA y = 1.2m
