a ventilation fan has blades has 0.25m in radius rotating at 20rpm. what is the tangential speed of each blade tip?
Vtangential - Omega *r
Conversion to radians is 2Pie radians
The Attempt at a Solution
I have tried everything I know and I am really hating physics right now. I can't seem to get this out.
I converted the rpm to radians like this
then I used the Vtangential equation
Its out - can someone please shed some light. I can't wait for the exam on Tuesday to be over. I have a teacher who can't even speak proper english let alone teach physics.
