The following corrections should be made to the original paper: in the original paper, the values of the s and r coefficients reported in Table 5 are not correct. As a consequence, the third paragraph in the second column on page 04015016-3 has to be changed as well.

On page 04015016-3, the original paragraph reads as follows: experimental values of coefficients s and r are once again different from the ones obtained through theoretical calculations in system B. In particular, reflected pressure waves in leg 3 are greater than the ones expected for higher flow rates, up to 8.5% in test B4, as reported in Table 5.
This paragraph should be corrected as follows:
Experimental values of coefficients s and r are once again different from the ones obtained through theoretical calculations in system B. In particular, reflected pressure waves in leg 3 are greater than the ones expected for higher flow rates, up to 6.1% in test B4, as reported in Table 5.
