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.
Horsepower can be calculated using the formula: Horsepower (HP) = (Torque (lb-ft) × RPM) / 5,252 where Torque is measured in pound-feet and RPM is the engine speed in revolutions per minute. This formula is commonly used in automotive applications to determine an engine's power output.
(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.
6.5 at 3600 rpm
7100rpm
18000 RPM
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 ==
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.
The Lawnmower Man was created in 1975.
Lawnmower Deth was created in 1987.
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
