Speed regulation is the percentage of speed change, generally this is only calculated on devices which are attempting to maintain a constant speed. For example, on some industry motors, they need to maintain a constant RPM. When the motor has weight bearing on it, it is called a load, and the speed may change slightly.
Formula:
high speed (or no load) = nL
Lowest speed (or full load) = fL
(nL - fL) / fL x 100 = % regulation.
example: 1700 rpm no load, 1500 rpm full load.
(1700 - 1500) / 1500 x 100
= 200 / 1500 x 100
= 0.1333 x 100
= roughly 13% speed regulation.

Does an apartment complex need speed bumps?
There is no regulation that requires them. But some sort of speed regulation is helpful, particularly if there are children in the area.

What is speed regulation and their formula?
Speed regulation is most often defined as the percentage change in speed of a motor or variable speed drive due to a specified change in load torque. The percentage change is usually a percentage of the base speed, where the base speed is the maximum speed or the maximum speed in the constant torque speed range. The change in load torque is usually specified as a change from 10% or 25% of rated torque to 90% or 100% of rated torque. Thus Regulation(%) = 100 X (Initial Speed - Final Speed) / Base Speed. Speed changes due to factors other than changes in load torque are usually quantified as a percentage "service deviation." Sometimes speed regulation is stated as two numbers such as 1%/3%. In that case, the first number is the "operating deviation," the percentage speed change due to load change, and the second number is the "service deviation," the percentage speed change due to all other factors. Factors other than load that can cause speed changes include temperature change, supply voltage change, etc.

What color and shape is a Regulation Sign?
A regulation sign is a sign that gives you the regulation for something. These signs are always in white and black and rectangle in shape. An example is a speed limit sign.
