A contracted weir 1.22 m long is placed in a rectangular channel 2.74 m wide. The height of the weir crest is 1.00 m and the head is 381 mm. Determine the flow, using c=0.52.
Question 2 For the square loop shown below, find the discharges in each pipe, AB, BC, CD and AD, using Hardy Cross analysis. All the pipes are at the same elevation, are 1 km long with a 300 mm diameter. Friction factor is 0.019. Begin the analysis at Point A, assuming that 60 liters/second (L/S) flows into AB and 40 L/S flows into AD. NOTES: Use AQ as: AQ EHL 2E(HL/Q) 1 L/S - 1,000 m³/s 100 L/S A D 40 L/S B 20 L/S +→

Topic: Hydraulics
Convert all units in SI. Round off to 2 significant figures. Use Francis Formula. A sharp-created weir 2ft high extends across a rectangular channel 8 ft wide conducting irrigation water. If the measured head is 4 3/4 in., determine the discharge.
HYDRAULICS Convert all units in SI. Round off to 2 significant figures. Use Francis Formula. A sharp-created weir 3.0 ft high extends across a rectangular channel, 20 ft wide, in which there is 100 cfs flowing. Determine the depth of water upstream from the weir.
Problem 3: Culvert Roughness A culvert transmits 0.45 m³/s of water from the pond at left (surface elevation 123.0 m) to the pond at right (surface elevation 122.0 m). L= 25 m and D = 50 cm. The flow is steady and uniform, and the pipe is completely full. Part A Use Bernoulli's equation to calculate the friction head loss. [m] Part B What is the average velocity? [m/s] Part C Calculate Darcy-Weisbach's friction factor 2. Part D Calculate Hazen-Williams's roughness coefficient Chw. Part E Calculate Manning's n with units.
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.
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.
