HYDRAULICS Convert all units in SI. Round off to 2 significant figures. Use Francis Formula. A rectangular channel 20 ft wide has a 3 ft depth of water flowing with a mean velocity of 2.45 ft per sec. Determine the height of standard sharp-created weir that will increase the depth in the channel of approach to 5 ft.
For a 6 ft wide rectangular channel, a hydraulic jump occurs according to the following figure. If the flowrate is 80 cfs and vi is 20 ft/s, find h2. h2
A hydraulic jump occurred in a rectangular channel of 5 m bottom width and flow rate of Q=21.5 m3/sec. If the water- depth before the jump was, Y=0.4 m , determine the water- depth after the jump. Notes: The answer should be in 2 decimal points. - No need to write the unit.

Q2/Béd width of an open channel is B = 40 (m), depth of water in the channel is y = 2 (m), longitudinal bed level slope is So = 0.001 and Manning's coefficient is n= 0.025 { m(l)/s}. Calculate the value of water flow rate in the channel. Find the Type of flow in the channel.
A short reach of a 2 m wide rectangular open channel has its bed level rising in the direction of flow at a slope of 1 in 10000. It carries a discharge of 4 m³/s and its Manning's roughness coefficient is 0.01. The flow in this reach is gradually varying. At a certain section in this reach, the depth of flow was measured as 0.5 m. The rate of change of the after depth with distance, dy/dx, at this section is (use g = 10 m/s²).

In the vertical wall of a reservoir (A) there is a drowned hole that it flows into another reservoir (B) with a real discharge speed of 4,5m/s. This one reservoir (B), in turn, has a square orifice with free discharge of the form shown in the figure. It requires a flow of 0,089 m³/s and there is no overflow of the system. Determine determine the area and edges of orifice 2. (See the image) Data: Orifice diameter 1 = 0.2m; Discharge coefficient for orifice 2 = 0.604; contraction coefficient for orifice 2 = 0.64. Consider both holessmall in relation to the depth of the reservoirs.
