A 5.6L V8 CI engine has a compression ratio of 20.0and a crevice volume of 5% of clearance volume. During the engine cycle, crevice volume pressure equals combustion chamber pressure while remaining at the cylinder wall temperature of180C. Cylinder conditions at the startof compression are 60C and 140 kPa and peaktemperature is 12,000 kPa. Cutoff ratio is 2.2. Calculate:1.Crevice volume of one cylinder2.Percent of air-fuel mixture in thecrevice volume at the end of compression3.Percent of air-fuel mixture in the crevice volume at the end of combustion

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
