Open Channel Flow

Open channel flow is a branch of fluid mechanics. It deals with the flow of fluid in an open conduit or free surface. In an open channel flow, gravity induces the flow of water whose surface is open to the air. This flow is free-falling rather than confined in rigid body conduits. The open channel flow depends upon two parameters that are the cross-section of the conduit and the velocity profile. Practical examples of open channel flow are streams, rivers, canals, and other drainage systems.In open channel flow, the cross-sectional area of at least one of the sides is exposed to air, and the surface of water faces atmospheric pressure. This flow is also known as free gravity flow. The cross-sectional area of the conduit can be either man-made or a natural channel. For instance, the flow in rivers and streams are natural conduits, and the flow in a canal and sanitary systems are man-made or engineered channels.

Water flows in a horizontal, rectangular channel initially 10 feet wide and 2 feet deep. The initial velocity is 6 ft/s. This flow encounters downstream a simultaneous downward step and constriction.

Water is drawn from an intake tower in Lake Ontario through a 3-km long precast reinforced concrete pipeline (Hazen-William’s C = 120) and delivered to the wet well of a low lift pumping station on shore which in turn supplies a water treatment plant. The pumping station is sized to deliver and will be operating at the maximum day flow rate of 2.65 m3/s. (a) If the design water elevation in the wet well is 70 m when the lake level is 74 m above MSL, determine the most economical pipe size for the intake (neglect local losses). (b) Compare the entrance and exit losses to the pipe friction losses to justify the assumption in (a). The entrance and exit loss coefficients can be assumed to be 1. (c) Sketch the hydraulic and energy grade lines. (d) Explain what would happen if the intake pipeline’s capacity was reduced but the pumping station is still operating at the same flow rate.
