    Understanding the Different Forms of the Ideal Gas Law and Their Applications

    That is helpful, although taht seems to be simply for the "normal" ideal gas law (at least normal to me) I'm having more difficulty I guess knowing what R is for the ideal gas law using specific volume. In my thermodynamics class right now, it's denoted as R bar (not unit of pressure) and when...

    Understanding the Different Forms of the Ideal Gas Law and Their Applications

    Hey I was hoping someone could be me a succinct method of knowing what form of the Ideal gas law I need to use and in particular the different R's associated with each form. Form my Thermodynamics class we use PV = nRT Pv = RT PV = mRT Little v being the specific volume (which changes the R...

    Calculating wheel torque from engine torque

    Okay that makes sense, I've found the rpm shift points and the rpm post shift, so I have my bounds, I also have the area under the curve between these rpm's for each gear (the graph is rpm vs torque) I'll do it out on paper to check if it works, but I'm hoping that since I'm assuming it takes 1...

    Calculating wheel torque from engine torque

    Right that's what I was trying, but because the torque (and therefore acceleration) is non constant, do I have to evaluate the acceleration at each time step dt or can I somehow calculate a net acceleration with net torque and total time?

    Calculating wheel torque from engine torque

    Okay, well if I multiply rpm*torque, how would I go about finding the actual power if I wanted to use that to calculate acceleration, given that, that product would only be in proportion to, not equal to power?

    Calculating wheel torque from engine torque

    Well that makes sense, although for now I'm working with torque data, if I did use power data, wouldn't I need power output for ever gear? Or would the shift point be the same in each gear?

    Calculating wheel torque from engine torque

    Thanks so much, exactly what I was looking for.

    Calculating wheel torque from engine torque

    Im currently writing a code to find the optimum rpm points to shift gears to maximize acceleration. Thus far I've found the shift points and the rpm's after an upshift, meaning I have my bounds on my rpm vs torque curve. For simplicity's sake I'm assuming and increase of 1000 rpm to take 1...
