It will be noted that with this basis of comparison, the rating of the horizontal type is slightly lower than that of the standard, whereas with the (actual) basis it was higher. It is doubtful if the Webre (vacuum) rating on the (corrected) basis can be accepted, as the steam pressures in these tests were so far below the assumed standard conditions that the density formula could hardly be considered applicable. Table 20 is made up from the averages of all tests for each type. It is probable, however, that a better rating would be obtained by using only the tests where conditions were favorable. Considering the four tests giving the highest coefficients for the standard and horizontal types the rating is: (Actual), Standard......................................... 1.00 Horizontal........................................ 1.06 (Corrected)-Standard......................................... 1.00 Horizontal.........................................96 The fairest comparison of the Lillie and Kestner types (film) will be obtained by using only the tests at Guanica, where the operating conditions were equally favorable for both types (see tests 1-to 6 inclusive). On this basis the ratings are: (Actual) Kestner........................................... 1.00 Lillie............................................. 1.17 By reference to the tables it will be noted that the horizontal efiects were of two kinds, viz., Wellner-Jelinek and Swenson, the former having tubes with a diameter of about 1%" and the latter 114." Tests 8 and 9 on the Wellner-Jelinek and tests 20 and 21 on the Swenson were made under conditions that should aiford a fair comparison, and giving the following relative...show more
