7. A rectangular, unfinished concrete channel of 38-ft width is laid on a slope of 8 ft/mi.
Determine the flow depth and Froude number of the flow if the flowrate is 400 ft³/s.
***Please MAKE SURE to include all parts that I have shown in the 8 steps here and follow them but also show work for the entire problem. Those are all correct I just need the entire worked out problem with all of the work.
***When answering the question MAKE SURE to use ALL of these steps and include them in the answer and don't answer the question in a different manner that is different than what is provided here as what is provided is correct (please include the work as well thanks I will like the answer):
1.correct equation: (ΔP / (ρg)) + ΔZ = f * (L / D) * (v^2 / 2g) + (v^2 / 2g) * ΣK_L
2.v = Q / A = 9.17 ft/s
3. Reynolds number: Re = (v * L) / ν = (v * L) / (ρ * μ) = 63,154
4.The pipe is smooth so: ε_d = 0
5.Friction factor from the Moody diagram: f = 0.020
6.Pressure difference: ΔP = P₁ - P₂ = P₁ - 8640 lb_f
7.Head loss due to elevation difference: ΔZ = Z₁ - Z₂ = -10 ft
8.Summation of pipe fittings and losses: ΣK_L = 0.2 + 7 + 2(1.5) + 0.05 = 10.25
9.values to plug in
Length of the pipe: L = 20 ft
Diameter of the pipe: D = 1/12 ft
Fluid density: ρ = 1.94 slugs/ft³
Gravitational acceleration: g = 32.2 ft/s²
