Air tank, compressor, car engine, heat exchanger, and insulation for everything except car engine and heat exchanger.Air into engine, cools off, warms up by heat exchanger, compresses, back to tank Repeat. 2 tanks, switch back and forth to keep pressure constant. Fill one, Use one, then switch.Doable?
i imagine, out of your question, that the stress and temperature of the air interior the tank do not count number number. you've defined the cylinder as being crammed at acceptable middle with 30F air at 15 PSI. artwork is then executed to move the cynlinder to the bottom position, with will cut back the stress by technique of the compression ratio. For this celebration, shall we anticipate 10::a million. The gas formulation is PV=nrT. For our applications, the stress cases the Volule divided by technique of Temperature is consistent. For this formulation, all temperatures are absolute temperatures. we are going to use the Rankine scale, which promises 459.67? to the Fahrenheit scale to grant Rankine ranges. what's the volume of the cylinder? shall we anticipate a large engine, like a 409 cubic inch displacement V8. that grants us a volume of fifty one.100 twenty 5 cubic inches for the cylinder. all of us understand the temperature, volume, and stress on the starting up. all of us understand the temperature and volume on the acceptable, and decide to understand the stress. Pi = stress preliminary Vi = volume preliminary Ti = Temperature preliminary Pf = stress very last Vf = volume very last Tf = Temperature very last Pi = 15 psi (given) Vi = 5.1125 (from compression ratio) Ti = 489.67?R Pf = unknown Vf = fifty one.100 twenty 5 (from assumption) Tf = 531.67?R (Pi * Vi)/Ti = (Pf * Vf)/Tf (15 * 5.1125) / 489.sixty seven = (Pf * fifty one.100 twenty 5) / 531.sixty seven fixing for Pf supplies Pf = a million.sixty 3 psi The temperature distinction between 30 ranges and seventy 2 ranges does no longer come on the fringe of creating up for the volume distinction between the acceptable and bottom of the stroke.
