RESULTS It will be noted that in each exhaust system the readings at the exhaust outlets was a mims reading thereby creating a suction, also that the Auxiliary exhaust system offers less resistance to the flow of exhaust gases than the regular stack exhaust, due to the absence of silencers. The data on the heat run that started at 1120 and ran until 1400 are contained on test chart Dwg. #FS 411-A. TEST NO, 2 MARCH 6 1951 The results of this test are all tabulated on test chart, Dwg. No. FS 411; test was run for a four hour interval with readings every thirty (30) mimates; diesel generator unit No. 1 alone was used for this test carrying full load, For the fuel consumption test, a 55 gallon ofl drum was used, and the amount of fuel oil was calculated for each 1/8" of depth. 5-320 This was
