please help me with it, urgent!

(A) - You have opened a consulting firm that specializes in chemical engineering insight for agriculture applications. A client comes to you seeking help in determining flow rates through an open, rectangular, passive irrigation channel (culvert) to his field. Thankfully you kept your ChE 310 Textbook and notice that Problem 3.9 details Manning's equation which can be used for this solution. You visit the client's field and make the following measurements: slope = 0.01 (rise over run) width = 2m depth = 0.5m roughness coefficient = 0.03 . Create a MATLAB function that calculates the velocity of water through this channel (output) given the above inputs (slope, width, depth, roughness). In an m-file script HW2_3.m, use your function and then calculate the volumetric flow rate (NOTE: not velocity) for your client's field. (B) - News quickly spreads of your firm's expertise in culvert calculations. You open your email one day to find an invitation from the UAE to design all of their state funded culverts. They attach the following Excel file with all their measurements 'culverts.xls' (Column 1-4 are roughness, slope, width, and depth respectively). In the M-file HW2_3.m, import the data from the Excel sheet, use the function in part (A) to help calculate the volumetric flow rate (NOTE: not velocity), and then export the calculated flow rate vector as a new Excel file. (C) - Adding on to HW2_3.m, use MATLAB to count the number of channels with flow rates greater than 100 m/s, which we consider to be poorly designed. What percentage of the designs fall in this poor category? Report this percentage to the command window.
