The Chezy coefficient (C) is used for determining water velocity in open channels and is defined as C = (1.49 ) *R2/6 where nis a roughness coefficient and Ris hydraulic radius in feet. Create a function that solves for the Chezy coefficient. Your function should call the arguments n and R from cells C7 and C9 in a worksheet. Use values of 0.012 forn and 1 for R Use your function to output to cell C11
