I'm practicing for the CSWP exam and I cannot get the correct mass for question 2 of segment 1.
I have tried two different modeling methods; 1 without equations and 1 with equations, but neither give the correct answer (16490.45 according to the practice exam).
I am getting the correct mass for question 1, using the equations method.
I have double checked the equation values which change for question 2, but still cannot find the error.
Screen shots attached show values for question 1 and 2.
Any help is greatly appreciated.
