I'm using pwr-tools software to calculate power and torque.

AI Thread Summary
The discussion centers on using pwr-tools software to calculate power and torque for a specific setup involving a 30" diameter stainless steel rim and a 1 horsepower BLDC motor. The user seeks to determine the torque at the output shaft of a reducer with a 5:1 ratio and 98% efficiency, specifically at 1200 RPM. Key calculations involve understanding the relationship between RPM, power, and torque, as well as applying the efficiency of the reducer. The user requests guidance on the steps needed to solve the problem and where they might be encountering difficulties. Clear calculations and methodology are essential for accurate results.

I'm using pwr-tools software to calculate power and torque. I'm not sure of the answer I'm getting is clear.
Problem:
30" diameter stainless steel rim with a 3" face. OD is 30"-ID is 29.5"
Rpm is 6000
The reducer is 98%efficient and the ratio is 5:1 (please use 98% in the calculation)
The prime mover is a bldc 1 horse power motor
What is the torque at the output shaft of the reducer at 1200rpm?

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
