Answer:
y ≈ 2.5
Explanation:
Given data:
bottom width is 3 m
side slope is 1:2
discharge is 10 m^3/s
slope is 0.004
manning roughness coefficient is 0.015
manning equation is written as

where R is hydraulic radius
S = bed slope



P is perimeter 

![Q = (2+2y) y) \times 1/0.015 [\frac{(3+2y) y}{(3+2\sqrt{5} y)}]^{2/3} 0.004^{1/2}](https://tex.z-dn.net/?f=Q%20%3D%20%282%2B2y%29%20y%29%20%5Ctimes%201%2F0.015%20%5B%5Cfrac%7B%283%2B2y%29%20y%7D%7B%283%2B2%5Csqrt%7B5%7D%20y%29%7D%5D%5E%7B2%2F3%7D%200.004%5E%7B1%2F2%7D)
solving for y![100 =(2+2y) y) \times (1/0.015) [\frac{(3+2y) y}{(3+2\sqrt{5} y)}]^{2/3} \times 0.004^{1/2}](https://tex.z-dn.net/?f=100%20%3D%282%2B2y%29%20y%29%20%5Ctimes%20%281%2F0.015%29%20%5B%5Cfrac%7B%283%2B2y%29%20y%7D%7B%283%2B2%5Csqrt%7B5%7D%20y%29%7D%5D%5E%7B2%2F3%7D%20%5Ctimes%200.004%5E%7B1%2F2%7D)
solving for y value by using iteration method ,we get
y ≈ 2.5
Answer:
System integration can be defined as the progressive linking and testing of system components to merge their functional and technical characteristics into a comprehensive interoperable system.
Explanation:
....
Using the knowledge of computational language in python it is possible to write a code that writes a list and defines the arrange.
<h3>Writing code in python:</h3>
<em>def isSorted(lyst):</em>
<em>if len(lyst) >= 0 and len(lyst) < 2:</em>
<em>return True</em>
<em>else:</em>
<em>for i in range(len(lyst)-1):</em>
<em>if lyst[i] > lyst[i+1]:</em>
<em>return False</em>
<em>return True</em>
<em>def main():</em>
<em>lyst = []</em>
<em>print(isSorted(lyst))</em>
<em>lyst = [1]</em>
<em>print(isSorted(lyst))</em>
<em>lyst = list(range(10))</em>
<em>print(isSorted(lyst))</em>
<em>lyst[9] = 3</em>
<em>print(isSorted(lyst))</em>
<em>main()</em>
