Two canals join to form a larger canal as shown in Video V10.6 and Fig. P10.80. Each of the three rectangular canals is lined with the same material and has the same bottom slope. The water depth in each is to be 2 m. Determine the width of the merged canal, b. Explain physically (i.e., without using any equations) why it is expected that the width of the merged canal is less than the combined widths of the two original canals (i.e., b 4 m 8 m 12 m).

ENGR 121 B Lecture Notes for 9/26/2016 Spencer Kociba Summary of Lecture: how to classify, categorize, modify and conduct operations using matrices and vectors in MATLAB (which stands for Matrix Laboratory) MATRICES ● Matrix: stores a set of values of the same type ○ every value is an element ○ Matrix = m rows, n columns ● Creating Matrices ○ Ex. >> m=[ 1,4,6; 7,8,10; 2,7,15; 3,7,8] becomes a 4x3 matrix ■ 1,4,6 = 1st row, 7,8,10 = 2nd row, etc. ■ ; indicates the end of a row ■ MATLAB will show an error if your elements and the size of the matrix don
