AI Thread Summary
To calculate the power required to turn a flywheel at a constant velocity, one can use the formula Energy = 1/2 * I * ω², where I is the moment of inertia and ω is the angular velocity in radians per second. The moment of inertia (I) can be calculated using I = m * r², with m being the mass and r the radius of the flywheel. If there are no losses such as friction or air resistance, theoretically, no power is needed to maintain constant angular velocity. To determine the power in horsepower, divide the energy by the time taken to reach the desired angular speed. Understanding these calculations is crucial for applications involving flywheels in mechanical systems.

How to calculate how much power required to turn a flywheel at constant velosity ? Suppose I have a flywheel of 24 inch diameter, width 5 inches,50kg and constant angular velosity is 1500 rpm. How do I calculate the required power (HP) to turn this or any other with different values?
 
Engineering news on Phys.org
If there are no losses (eg no friction or air resistance) then it takes no power to keep it running at a constant angular velocity.
 
If there are no losses you can use the formulaEnergy= 1/2 * I * W2

I= m*r2 * constant depending on shape

then divide by the time you want it to reach the angular speed you want (e.g in 10 sec ...)
 

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...

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...

TL;DR Summary: Heard in the news about using sonar to locate the sub Hello : After the sinking of the ship near the Greek shores , carrying of alot of people , there was another accident that include 5 tourists and a submarine visiting the titanic , which went missing Some technical notes captured my attention, that there us few sonar devices are hearing sounds repeated every 30 seconds , but they are not able to locate the source Is it possible that the sound waves are reflecting from...
