A) Use the Excel Regression package to find an accurate equation to relate the water velocity with the space variables x and y, determine coefficients and R2 value for the following function: v(x, y) = C0 + C1 x +C2 y + C3 x 2 +C4 y2+C5 xy
b) Display your results in a surface or contour plot. Now that you have an equation, you can create a two dimensional array showing velocity for different values (x. y), with x values between 0 and 13, and y values between 0 and 4. x(m) (m)v(m/s) 0 0.000000 3 0.187480 0.100967 3 0.280524 10.234002 4 0.382953 2 0.338599 0.643920 1 0.315909 0.421943 0 0.279736 3 0.430427 0.185249 2 0.145312 0.168902 0 0.074963 2 0.072238 0 0.000000 1 0.033413 4 0.090294 4 12 13 13
