A large twelve-cylinder, 460 L, two-stroke cycle engine operates using dual fuel. 92% of the intake air is used for stoichiometric combustion of methanol, while 8% is used for stoichiometric combustion of light diesel fuel for ignition. The engine operates at 195 RPM with a volumetric efficiency of 93%. The methanol is input during the intake stroke, while diesel fuel is injected into each cylinder by a single injector from 15° bTDC to 6° aTDC.

Calculate:

(a) Mass flow rate of air into engine. [kg/sec]

(b) Mass flow rate of methanol into engine. [kg/sec]

(c) Mass flow rate of diesel fuel through an injector. [kg/sec]
