rpm. vs rpm

rpm.

This is correct when referring to revolutions per minute in a technical or scientific context where the period is necessary.

Use "rpm." when writing about revolutions per minute in technical or scientific contexts to indicate the abbreviation with the necessary period.

Examples:

  • The engine's maximum speed is 5000 rpm.
  • The fan rotates at 1200 rpm.
  • Jeremy, give it 1,500 rpm.
  • All right, let's start at 6,000 rpm.
  • Matter of fact, I spun at 120 rpm.
  • Adjust the peristaltic pumps to deliver 250 ± 25 ml/h of the organic medium (without test chemical) into the inclined tubes, which are rotated at 18 ± 2 rpm.
  • Both engines indicate 50 rpm.
  • Both main engines 50 rpm.
  • We need to release enough water to make this pulley rotate and make this alternator spin at the speed of 1500 rpm.
  • When necessary for lubrication and seal running-in, compressor may be run in between preconditioning and test during a minimum period of 1 min at minimum speed of 200 rpm.
  • Endurance rotation is 67, 68 RPM.
  • Both main engines 50 rpm.
  • Only applicable for engines with maximum test speed <= 3400 rpm.
  • Both main engines at 50 rpm.
  • Here we are. 520 horsepower at 6300 rpm.
  • The 458 doesn't have 500 torques at any rpm.
  • The styling's a lot better, and also a higher rpm.
  • noise must be measured at the maximum rpm using slow sound-level meter response i.e. in the gear giving the speed nearest to 7.5 km/h at the rated rpm.
  • Zero point five-nine horsepower, 6,500 RPM.
  • Thought I heard a bit of a whine around about 7,000 RPM.
  • 1,300 RPM. I'm doing very nearly the top speed of six.
  • The same indirect means and the same "supportive" measures can be used to make maximum or recommended prices work as RPM.

Alternatives:

  • revolutions per minute.
  • rev/min.
  • rev/min
  • rotations per minute.
  • rotations/min.

rpm

This is correct when mentioning revolutions per minute in a casual or general context.

Use "rpm " when talking about revolutions per minute in casual or general contexts without the need for a period after the abbreviation.

  • The record player spins at 45 rpm
  • Centrifuge the cold extract for 5 minutes at approximately 2000 rpm and decant immediately.
  • Close the cap and centrifuge at 10000 rpm for 1 min.
  • The resulting suspension is centrifuged for one hour at 10000 rpm at 4 gC.
  • Only applicable for engines with maximum test speed <= 3400 rpm.
  • Centrifuge at 10000 rpm for 10 minutes.
  • Centrifuge at 2000 to 3000 rpm to pellet the cells.
  • Jeremy, give it 1,500 rpm.
  • Incubate 5 minutes at room temperature and centrifuge at 10000 rpm for 1 min.
  • Percentage of maximum rpm [5]
  • Percentage of maximum torque at rpm stated
  • I'm just going to take it up a little bit more, 2,300 rpm a side.
  • All right, let's start at 6,000 rpm.
  • b. Rotary speed of 700 rpm or more;
  • Matter of fact, I spun at 120 rpm.
  • What, going around at 5,000 rpm?
  • At a speed of 3000 rpm;
  • Engine rated power: [kW rpm]
  • When using the binary distributions (most often rpm packages), it is enough to have the & kde; and QT binaries installed.
  • Industrial suction fans spin at more than 1,400 rpm and weigh as much as 500 pounds.
  • Probably about six rpm, so you won't wake all the neighbors.
