It depends upon the circumference of the rotating object such as a wheel. Deriving the formula, let the radius of the wheel be r then, the circumference of a circle is = (2 X (pi) X r) the total distance covered by the wheel in one min = (2 X (pi) X r) X rpm now, if the object's diameter is measured in meters then the formula would be, (2 X (pi) X r X rpm X 60) / 1000 else if in different unit then just convert it to meters
It depends on the size of your rotor g=(1.118x10^-5)xradius of rotor in cm x speed of centrifuge in rev/min^2
Your engine is not running or your "RPM gauge" is broken.
5500 rpm
122 cubic feet to rpm??
18000 RPM
7100rpm
The formula for RPM is ; RPM = Hz x (120 (constant)) divided by the # of poles. Number of poles a motor has; # of poles = Hz x (120 (constant)) / RPM.
There is no standard conversion between the two.
The formula for RPM is, RPM = Hz x 60 x 2/# of poles the motor has. To answer this question more information needs to be stated.
== distance x time== speed ==
To calculate burst RPM (rotations per minute), you need to know the burst speed of the machine in revolutions per second. You can then multiply this value by 60 to convert it to RPM. The formula for calculating burst RPM is: Burst RPM = Burst speed (revolutions per second) * 60.
It is based on the RPM of the motor. Use the following formulas for 50 and 60 Hertz. The mathematical formula is Frequency in Hertz times 60 (for seconds in a minute) times two (for the positive and negative pulses in the cycle) divided by the number of poles. For 60 hertz, the formula would be, 60 x 60 x 2 = 7,200 no load RPM divided by the number of poles will give you the nameplate RPM of the motor. eg from above formula 7200/2 pole = 3600 RPM, 7200/4 = 1800 RPM, 7200/6 = 1200 RPM
To calculate horsepower you need the car's torque numbers. To find the horsepower, the formula HP=(RPM*T)/5252. The "HP" stands for "horse power", the "T" in the formula stands for "torque " and RPM stands for the RPM values. To calculate the horse power of an electric motor, you use the formula HP= (V*l*eff)/746. V=voltage, l=amps, and eff= efficiency.
RPM is an expression of rotational velocity. It is the number of revolutions a rotating object makes on its own axis in one minute. RPM is used to calculate horsepower, linear velocity, gear ratios, and tangential velocity. The formula for roller rpm = Distance / Circumference.
A Formula One engine reaches 18,000 RPMs.
450 torque is approx. 260 HP for an engine turning at 3050 RPM or 308 HP for and engine turning 3600 RPM, based on the formula ......torque X rpm/5252 = HP
