The formula to calculate the missing variable for an air compressor is:
\[ Q = \frac{D \times N}{1728} \]
Where:
An air compressor is a device that converts power using an electric motor, diesel or gasoline engine, into potential energy stored in pressurized air. By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. When the tank’s pressure reaches its engineered upper limit, the air compressor shuts off. The compressed air is then held in the tank until called into use. The energy contained in the compressed air can be used for a variety of applications, including powering pneumatic tools, inflating tires, and operating machinery.
Let's assume the following values:
Using the formula to calculate the speed (N):
\[ N = \frac{Q \times 1728}{D} = \frac{10 \times 1728}{50} = 345.6 \text{ RPM} \]
The Speed (N) is 345.6 RPM.
