Derivative Material

AI Thread Summary

The material derivative, represented as Dρ/Dt, describes how a scalar quantity ρ changes over time and as it moves through space. This understanding is affirmed by participants in the discussion, confirming that the material derivative captures both temporal and spatial variations. The concept is crucial in fields like fluid dynamics, where it helps analyze the behavior of quantities within moving fluids. Overall, the explanation provided aligns well with the fundamental principles of the material derivative. Understanding this concept is essential for applying it effectively in various scientific contexts.

hey pf! can someone please tell me if my understanding of the material derivative operating over some scalar \rho is correct? basically, from my understanding if we take \frac{ D \rho}{D t} this will tell us how \rho changes as time changes AND how \rho changes as we move our little piece of \rho through space. is this correct?

thanks!

Yeah, I would say that's pretty much correct.

Thread 'Looking for dyno verified experiences with turbocharged 2-strokes'

Came across this forum and posts by Bluechipx about his real world experience with this subject while searching the web. Am building a turbo 2-stroke for Bonneville. Would be interested in hearing from anyone else with real world dyno verified experience on the subject. Been racing 2-strokes since '67.

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...

Thread 'HP Required to move a robot 10meters at 1.5m/sec'

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...
