Thrust

AI Thread Summary

A leaf blower with a capacity of 450 cfm at 120 mph generates approximately 3 pounds-force of thrust. The thrust calculation is based on the formula involving volumetric flow rate, air density, and velocity. A link to a computational tool is provided for further assistance in verifying the calculations. This information is crucial for those looking to create a leaf blower-powered bike. Understanding the thrust output is essential for the design and functionality of the bike.

Hi I want to make a leaf blower powered bike, And I need to know how much pounds of thrust Would I get from one leaf blower that puts out 450 cfm at 120 mph? Please help me solve this problem

(Your help will be highly appreciated)

About 3 pounds-force.

Thrust = volumetric flow rate *density * velocity

Thank you so very much

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks

Thread 'Linear generator prototype'

i want to just test a linear generator with galvanometer , the magnet is N28 and the wire (Cu) is of 0.6mm thikness and 10m long , but galvanometer dont show anthing , The core is PLA material (3d printed) The magnet size if 28mm * 10mm * 5mm

Thread 'Fundamental Probability'

If the universe is fundamentally probabilistic, and all possible outcomes are realized in some branch of the multiverse, does that invalidate the concept of scientific inquiry? If knowledge is merely a description of one particular branch of reality, does it have any inherent value?
