Speaking from past experience, soybean projects always do well in science fairs. The soybean industry is growing and so a child that demonstrates a project growing soybeans or using them to make a product could do really well in a science fair.
(Angular displacement divided by 360 degrees or pi radians)/(Time measured in minutes)
Friction power (FP) can be calculated using the formula FP = (Torque × Angular Speed) / 5252, where Torque is in pound-feet and Angular Speed is in revolutions per minute (RPM). Brake horsepower (BHP) is determined by the formula BHP = (Torque × RPM) / 5252 as well, but it reflects the engine's output power before losses from friction and other factors. Both formulas highlight the relationship between torque and RPM in measuring engine performance.
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
Power in horsepower (hp) can be calculated using the formula: [ \text{hp} = \frac{\text{Torque (lb-ft)} \times \text{RPM}}{5252} ] This formula relates torque (in pound-feet) and rotational speed (in revolutions per minute, RPM) to derive horsepower. Alternatively, for electrical power, it can be calculated as: [ \text{hp} = \frac{\text{Watts}}{746} ] where Watts is the power in watts.
Generators typically run at 3600 RPM to produce alternating current (AC) at a frequency of 60 Hz, which is standard in North America. This speed is derived from the formula for synchronous speed, where the number of poles in the generator affects the RPM; for a 2-pole generator, 3600 RPM corresponds to 60 Hz (60 cycles per second). Operating at this speed ensures efficient energy conversion and stable output frequency, which is crucial for electrical systems.
6.5 at 3600 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.

It all depends on the pullys you have really, the hp only helps how fast you get there or if your even going to get there. The motors rpm range also plays a role.
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.
