complete solution thankyou
-) A 3 foot diameter culvert has a free discharge and steep slope. The entrance loss
coefficient is K. = 0.5. The headwater is 6 feet above the invert of the culvert. What is the discharge?
If the headwater continued to rise to 8 feet and the road level is at 7 feet, what is the flow given a
road length of 15 feet and C = 1.5? (Recall Ca = 1/(1+K)/2)
1. A trapezoidal concrete-lined
ditch has a bottom width of 3 ft,
a depth of 2 ft, and side slopes of 2:1. Estimate the discharge if
the channel slope is 1.0. What is the velocity? The Froude
number?
