🔍 Key Concepts

• Centrifugal force and bowl radius in a centrifuge • Effect of rotational speed (RPM) on separation efficiency • How bowl diameter influences windage (air resistance) and friction losses

💭 Think About

• How does centrifugal force relate to radius and speed? Think about which variable must change when radius becomes smaller but you still want strong separating force. • What happens to air resistance (windage) and mechanical friction when you compare a large diameter bowl to a small diameter bowl at high speeds? • Which choice actually explains why a tubular bowl can safely and practically run at a much higher speed than a disk-type bowl?

✅ Before You Answer

• Recall or derive the relation: centrifugal force depends on radius and angular velocity (ω). • Check which options describe a consequence of narrow diameter vs which describe the purpose for running at higher speed. • Eliminate any option that talks about a part or feature that does not logically require more than double the speed compared with a disk-type bowl.

Question 1 of 20

The rotating speed of the tubular bowl centrifuge is more than twice that of the disk-type. The reason for this is __________.

the drag bushing is used to permit the higher speed of rotation

to produce a nearly equal magnitude of centrifugal force

a narrow diameter bowl is not affected as much by windage losses as a larger diameter bowl

the friction affecting rotation is not as significant with a narrow diameter bowl
