It takes a man 12.5 hours to complete a 500-mile trip in his automobile, during which 18 gallons of gasoline are consumed. during this trip, the average emissions index for carbon monoxide is (ei)co = 28 (gm/s)co / (kg/s)fuel. the density of liquid gasoline is 0.692 kg/l. calculate: fuel economy in english units. [mpg] fuel consumption rate using standard si units of l/100 km. amount of co emitted to environment during trip. [kg]

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines

Asimple rankine cycle uses water as the working fluid. the water enters the turbine at 10 mpa and 480c while the condenser operates at 6 kpa. if the turbine has an isentropic efficiency of 80 percent while the pump has an isentropic efficiency of 70 percent determine the thermal efficiency
