A compressed air car has several advantages over conventional vehicles - it has zero emissions, refueling can be done at home and there is no hazardous or rare battery chemical to deal with. The engine of such a car relies on the expansion of compressed air from a tank to proviide power. According to a magazine article, one of handful of planned air cars models can hit 68 MPH and has a range of 125 miles. it will take only a few minutes to refuel at gas stations equipped with custom air compressor units; it should cost around $2 to fill the car's carbon fiber tanks with 340 liters of air at 4350 PSI. A)obtain the maximum work that can be obtained from the compressed air tank with the volume and pressure stated above. what is the effective mileage of this engine (miles per gallon of gasoline)? One gallon of gasoline provides 130 MJ of energy when burned. B) calculate the power required to run the custom air compressor units mentioned in the article, in order to allow refilling of tanks 5 min. What is the cost of electricity in $/KWh given $2 cost estimate for refuel
Air can be considered an ideal gas with Cv=5R/2. State all assumptions
