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...- Jack Duncan

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...- Jack Duncan

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...- Jack Duncan

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?- Jack Duncan

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?- Jack Duncan

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?- Jack Duncan

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...- Jack Duncan
