Jack, Thanks for your help, I have made a powerpoint slideshow which basically is outlined like this:Traditional 4-stroke otto cycle engines use air which is charged at the current ambient air pressure and density, at higher speeds these engines have problems putting charge into the cylinders...

Jack, How is useful work be extracted from the exhaust gasses? I would imagine through the use of exhaust to spin a turbine, but the website that you directed me to is a little bit strange, is it trying to show the correlation between the work it can produce and the mass of air which is...

Hi, 1. I have a question all based upon a 100kg satellite in orbit 620km above Earth's surface, I need to find the total energy (at rest), kinetic energy (in orbit), and binding energy (in orbit) of said satellite.2. I have tried to get the answer for the kinetic energy in orbit using: 1/2mv^2...

Jack Action, Without a turbocharger to increase the volumetric efficiency of an internal combustion engine, how can I explain the effectiveness of inputting of charge into a naturally aspirated engine? My mind wants to head to the simple direction of, a piston pushes exhaust out during the...

jack action, When you say that as the speed increases and the temperature drops, are you referring to the air which is being pulled into the system? Also, how does the polytropic process demonstrate that both density and temperature will increase? I have tried my best to understand through...

Hi everyone, I need to do a presentation to a high school class about the physics behind a turbocharger and was looking for some help getting which principals/laws explain what happens when a turbocharger is used within a car i.e.; Thermodynamics, gas laws. I just need a direction in which...
