A 6.8-liter, in-line, eight-cylinder CI engine has a compression ratio rc = 18.5 and a crevice volume equal to 3% of the clearance volume. During the engine cycle pressure ill. the crevice volume equals combustion chamber pressure while remaining at the cylinder wall temperature of 190°C. Cylinder conditions at the start of compression are 75°C and 120 kPa, and peak pressure is 11,000 kPa. Cutoff ratio is f3 = 2.3. Calculate: (a) Crevice volume of one cylinder. [em3] (b) Percent of air-fuel mixture in the crevice volume at the end of compression. [%] (c) Percent of air-fuel mixture in the crevice volume at the end of combustion. [%]

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
