    Energy Estimate
AI Thread Summary
To estimate the energy required for machine parts like turning a valve, knowing the torque is crucial, as it allows for calculating work in joules. The accuracy of the estimate largely depends on the specific machine and its components. Measuring the energy input and output is essential for assessing machine efficiency, including accounting for negative work throughout the system. Various equations and tools can assist in these calculations, but specifics will vary based on the machine's design. Understanding these factors is key to accurately estimating energy usage.

Hello Folks, How would I estimate the energy required for machine parts, such as turning a valve? we're talking joules? aye? could i estimate it fairly accurate? any help as to what equations and tools i would use?

im basically wanting to measure the efficiency of a machine... the energy put in, and the energy product put out, that would mean i have to measure all the "negative work?!" put about from the begining-through cog to cog-to the end...where to start?

If you know the torque required to turn the valve, then you can calculate work in joules quite easily. Other than that, it depends a lot on the specifics of the machine.
 

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...
