CFM, standing for Cubic Feet per Minute, is a measurement of the amount of a material (usually a gas or liquid), measured in cubic feet, that passes through a given spot over the interval of one minute.
RPM, standing for Rotations per Minute, is a measurement of the number of full rotations (360 degrees) that something makes over the interval of one minute.
The difference between the two is that one is a measurement of Volume vs. Time whereas the other is Rotation Distance vs. Time.

1. ASSUMING AIR DENSITY AND FAN BLADE DIAMETER IS CONSTANT OR THE SAME --THE LATTER (1750 RPM) DELIVERS MORE CFM WHETHER BELT DRIVEN OR DIRECT COUPLED -- SAME HP RATING OF MOTOR. 2. 1250 RPM FAN CAN MATCH THE CFM OF 1750 RPM FAN --- CHANGE OR ADJUST THE PITCH OF 1250 RPM FAN BLADE. 3. 1250 RPM FAN CAN DELIVER MORE CFM THAN THE 1750 RPM FAN --- REPLACE FAN BLADE. 4. 1250 RPM FAN CAN DELIVER MORE CFM THAN THE 1750 RPM FAN --- REPLACE WITH BIGGER HORSE POWER.

RPM stands for Revolutions-Per-Minute, and is counted at the crankshaft. At 3000 RPM the engine is spinning twice as fast as at 1500 RPM.
To determine the RPM (revolutions per minute) related to 376 CFM (cubic feet per minute), you need additional information, such as the size and design of the fan or blower, as well as the specific application. Typically, fan performance is characterized by its airflow at a certain RPM, which can vary widely based on factors like blade design and diameter. If you have a specific fan model in mind or additional parameters, you could consult the manufacturer's specifications or use fan performance curves to find the corresponding RPM for 376 CFM.
rated rpm is the maximum number of complete rotations that a rotor can rotate for every minute

Difference between Torque and load
Yes, you will see a difference in performance, read tests and write tests. As rule, 5400 rpm hard drives are faster and perform better.
7,200 revolutions per minute compared to 5,400 revolutions per minute.
The recommended CFM rating for a range hood is typically between 150 to 300 CFM for every linear foot of the stove.
To calculate sensible heat, you can use the formula: Sensible Heat (BTU/hr) = 1.08 x CFM x Temperature Difference (°F). Just multiply the CFM value by 1.08 and then by the temperature difference in Fahrenheit to get the sensible heat in BTU per hour.
