An engine cylinder contains 7 x 10-5 kg of fuel with a heat of combustion, e: of 45,000 kj/kg. the volume vi at top dead center is 0.15x 10-3 m3, and the volume v2 at bottom dead center is 1.50 x 10-3 m3. the air-fuel ratio is 16: 1, and the mixture temperature ti at the start of compression is 300 k modeling the compression and combustion as an ideal gas (y=1.4, c 0.71 kj/kg k) otto cycle, (a) what is the maximum temperature t3 and pressure p (b) what is the pressure p at the start of compression?

3. on your graph, the data points between the black squares are data for elements with atomic numbers 3 through 9. locate these elements on your periodic table. what term or description would you use to identify these elements with respect to the periodic table?

Na food processing facility, a spherical container of inner radius r1 5 40 cm, outer radius r2 5 41 cm, and ther- mal conductivity k 5 1.5 w/m · k is used to store hot water and to keep it at 100°c at all times. to accomplish this, the outer surface of the container is wrapped with a 800-w electric strip heater and then insulated. the temperature of the inner surface of the container is observed to be nearly 120°c at all times. as- suming 10 percent of the heat generated in the heater is lost through the insulation, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the container, (b) obtain a relation for the variation of temperature in the container material by solving the differential equation, and (c) evaluate the outer surface tempera- ture of the container. also determine how much water at 100°c this tank can supply steadily if the cold water enters at 20°c.

What is friction? how does it affect the motion of an object?
