The relationship between gallons per minute (gpm) and fixture unit is not constant, but varies with the number of fixture units. For example, 1000 FU is equivalent to 220 gpm, but 2000 FU is not double that, but is only 1.5 times as much, or 330 gpm.

(RPM=Revolutions Per Minute) The variable valve timing system controls when the valves are opened in the engine to either increase power or fuel economy. Lastly, the ECM controls the ignition timing, this is the position at which the spark plug is fired within the combustion cycle.

CFM stands for Cubic Feet per Minute and is the most common way to measure airflow. Areas are measured in square units (like square feet). Volumes (like a room full of air) are measured in cubic units — CFM determines how much cubic feet can be moved or exchanged each minute.

Flow is a measure of air output in terms of volume per unit of time. The common units are litres per minute, cubic feet per minute (CFM), etc. Velocity refers to how fast the air is moving in distance per unit of time.

Rounds Per Minute, represented here using "RPM", is the speed by which a magazine is emptied. This metric is tied to the minute, so the number is the number of bullets that can be put downrange in effective combat (taking into account reload time) per minute.

Actual cubic feet per minute (ACFM) is a unit of volumetric flow. ... This is the actual gas delivery with reference to inlet conditions, whereas cubic foot per minute (CFM) is an unqualified term and should only be used in general and never accepted as a specific definition without explanation.

The major differences between YUM and RPM are that yum knows how to resolve dependencies and can source these additional packages when doing its work. ... Both tools can perform an install, and RPM will even allow you to install multiple versions simultaneously, but YUM will tell you that that package is already installed.

More information from the unit converter The answer is 60. We assume you are converting between RPM and revolution/second. You can view more details on each measurement unit: RPM or revolutions per second The SI derived unit for frequency is the hertz. 1 hertz is equal to 60 RPM, or 1 revolutions per second.

CFM and SCFM CFM stands for cubic feet per minute. This is the air flow or air volume that a compressor can supply - or its output. Many pneumatic power tools require a CFM of about 5, but it really varies. A pneumatic stapler might just need 0.3 CFM, while a framing nailer may require 2.2 CFM.

Study the formula to convert horsepower between RPM. Work is equal to the torque multiplied by the time. The equation is therefore one horsepower = torque * RPM / 5252. The constant 5252 is a result of converting RPM to radians per second, and of using the definition of horsepower.

The new RGC coils offer adjustable airflow, while the older RPM coils do not. The RGC coils are pretty airy even with the air over halfway closed, while the RPM coils have a good amount of air for a slightly restricted DL by default.

A standard measurement of airflow that indicates how many cubic feet of air pass by a stationary point in one minute. The higher the number, the more air is being forced through the system. The volumetric flow rate of a liquid or gas in cubic feet per minute. 1 CFM equals approximately 0.47 liter per second.
