Find the approximate flow rate at which water will flow in a conduit shaped in the form of an equilateral triangle if the head lost is 5m per kilometer length. The cross-sectional area of the duct is 0.075m^2. Assume f = 0.0155

Determine the radius of the orifice that will allow a tank of horizontal cross-section of 2.5 m^2 to have its liquid surface draw down at the rate of 0.2 m/s for a constant head of 4m on the orifice with Cc= 0.66 and Cv= 0.96

Example 12.3. A small reservoir has a spillway crest elevation 200.0 m. Above this elevation, the storage and outflow from the reservoir can be expressed as: Storage: S=36000 + 18000y m³, Outflow Q=10y m³/s, where y is height of water above spillway crest in m. Route an inflow hydrograph which can be approximated by a triangle as: 1=0 at t=0, 1=30 m³/s at t=6 h and I = 0 at t = 26 h Assume at t= 0.y=0 and use At = 2 h
