The linear speed of a body revolving at 1200 RPM in a circular path of 0.8 meter radius would be closed to?
Circumference of the path = pi times the diameter = 2 pi times the radius = 1.6 pi.1200 rpm = 1200 circumferences per minute = (1,200 x 1.6 pi) = 1,920 pi inches/min= 6,031.9 inches/minute (rounded)= 502.7 feet/minute (rounded)= 5.71 miles/hour (rounded)
How do you convert radian to revolution per minute?
"Radian" is a distance. "Revolution per minute" is a speed. Those two units measure different quantities, and they don't convert into each other. It'll help to know that 1 revolution is (2 pi) radians. So "one revolution per minute" is "2 pi radians per minute", etc.
How do you convert RPM to radians per second?
(x radians / second) x (1 revolution / 2 pi radians) x (60 seconds / minute)= (60x) / (2 pi) (revolution / minute)Multiply (radians per sec) by (60)/(2 pi) = 9.5493(rounded) to get RPM.
How do you convert revolution per min to rad per second?
('X' rev/minute) x (2 pi radian/rev) x (1 minute/60 sec) = 2 pi X/60 = 0.10472 Xrad/sec (rounded)
Find the speed of a vehicle whose wheels are 20 inches in diameter are making 53 rotations per minute.?
each rotation = circumference = (pi) x (diameter) = 20 pi inches(53 rotation/minute) x (20 (pi) inch/rotation) x (60 minute/hour) x ( 1 foot/12 inch) x (1 mile/5,280 feet) =(53 x 20 pi x 60)/(12 x 5,280) = 3.153miles/hour (rounded)
