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.

What is the formula for RPM?
(Angular displacement divided by 360 degrees or pi radians)/(Time measured in minutes)
What is the formula for converting RPM to kph?
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
What is the formula for converting g into RPM?
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
Why is your RPM at zero?
Your engine is not running or your "RPM gauge" is broken.
How many paperclips are in a yard?
It only takes one to damage the lawnmower.
How much hp does a GCV190 gas honda lawnmower have?
6.5 at 3600 rpm
What is red line for formula 1 engine?
18000 RPM
What rpm should your Briggs world formula run?
7100rpm
What is the maximum RPM does a 3 phase motor run at?
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.
What is the formula for converting RPM to kmh?
There is no standard conversion between the two.
How much rpm for 12 volt ac motor?
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.
What is the formula to calculate speed from RPM of an engine?
== distance x time== speed ==
What is the formula for revolution?
Rpm= Surface x 12 / D x 3,1416
How fast does an industrial lawnmower go?
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.
How do you tell how many poles a 3 phase 480 volt motor has?
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
How is horsepower calculated exactly?
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.
Calculation of RPM of roller crusher?
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.
