Feel free to correct me if I'm wrong.
Question 76 in the PE Chemical Practice exam involves the calculation of an integral to determine cumulative production. The solution appears to evaluate the *indefinite* integral correctly, but does not determine the value of the integration constant for the starting condition (Q=0 at tao = 0 hours of uptime), and proceeds to determine the solution from the indefinite integral (with the integration constant omitted). By correctly determining first the value of the integration constant, a different answer is reached than the one arrived at in the solution.
This would perhaps be easier to explain if I posted the solution in its entirety, but I'd rather not risk copyright infringement (I'm an engineer, not an IP lawyer).
Has anyone else noticed this?
