- bliuzodt to mopolb 9. If machine parts are degreased by means of kerosene as shown in the diagram, how much kerosene make-up is needed per day? How much kerosene has to enter the degreasing vat per day? There are about 3 lb of grease per 100 lb of machine parts, and 60 tons of machine parts are processed each day. Five thousand pounds of kerosene (the 10% solution) are carried away by the machine parts each day but drip off and are caught and put back in the degreasing vat. Two hundred pounds of the 10% solution are lost each day from the vat by evaporation, spillage, or by being carried away.Thermodynamics-Processes of Gases show solution step by step with units answer it correctlya) Compute the air-fuel ratio by weight used in an engine if the exhaust gas analysis in percent by volume dry shows: CO2 = 12.4%, O2 = 3.2%, CO = 0.1%, H2 = 0.2%, CH4 = 0.3%. b) Find also the atomic ratio H/C of the fuel used.
