Equation 8-21 was derived by taking the derivative of Equation 8-19, setting this to zero and solving for \(x m\), the maximum rate. Perform the same procedure on Equation 8-20, which applies for small values of \(B\). Example 8-2 determines a value of \(x m\) using the exact Equation 8-21. Compute \(x m\) using the equation derived for this problem and compare to the more detailed result. What is the percentage error?
