The Hаzen-Williаms Equаtiоn tо calculate the velоcity of water flowing in a pipe:    can also be written as: v = 0.849 * C * (A/p)^0.63 * S^0.54 where: v is the velocity of water flowing in the pipe (in m/s). C is the roughness coefficient (no unit) and has value 130 for new cast iron. A/p is the hydraulic radius of the pipe (in m). S is the drop in elevation divided by distance of flow (no unit). Given the experimental data: Data: Pipe 1: Pipe 2: Pipe 3: A/p (m) 0.0142 0.0137 0.0125 S (no unit) 0.532 0.527 0.516 Write a program using the programming language taught in this class to find v.  1. Start your program with the good programming practice taught in class.  2. Define: Variable C to be the constant value. Variable Ap to be a vector of the three measured values of A/p.  Variable S to be a vector of the three values of S. 3. Compute v in terms of C, Ap, and S using vector operation. (Only apply the dot operators where needed. Unnecessary dot operators are penalized.) The command window should display only the values of v. 4. Create a plot with S in the horizontal dimension and v in the vertical dimension. Title the plot with "Water pipe profile". Label the horizontal dimension with "Slope of pipe". Label the vertical dimension with "Water velocity".
