1. By convention, pressure drop is treated as a positive value. Therefore, Eq. (11) should be as follows, i.e., without the negative sign on the right-hand side:
2. The expression for pressure drop due to the film-slug transition, Eq. (19) had a factor of 2 in the denominator, which should be removed, as shown below:
3. The value of the coefficient, a, in Eq. (21), currently listed as 2436.9 in the text following the equation, should be changed to For Eq. (24), the coefficient should be: instead of 996.5.
