CCT Pneumatic Principles & Air Flow Mechanics 2

Question 1

What does CFM stand for in Casper pneumatic tube system blower specifications?

Accepted Answer

Cubic Feet per Minute

Answer

Carrier Flow Management

Answer

Central Fan Module

Answer

Compressed Force Measurement

Question 2

How does installation at high altitude affect Casper pneumatic tube system performance?

Accepted Answer

Reduced air density at altitude requires increased blower capacity to maintain performance

Answer

Performance improves because air resistance is lower at altitude

Answer

Altitude has no measurable effect on pneumatic system performance

Answer

Higher altitude automatically increases carrier speed due to thinner air

Question 3

What is the function of an inlet air filter in a Casper pneumatic tube system?

Accepted Answer

To remove dust, debris, and particles from the airstream before they reach the blower

Answer

To increase the velocity of air entering the blower

Answer

To measure the volume of airflow entering the system

Answer

To reverse airflow direction during bidirectional operation

Question 4

In pneumatic tube system airflow analysis, what does 'static pressure' represent?

Accepted Answer

The resistance force that the blower must overcome to push air through the system

Answer

The pressure measured only when carriers are actively moving

Answer

The speed of air measured at the center of the tube cross-section

Answer

The weight of a stationary carrier resting in the tube

Question 5

In a bidirectional Casper pneumatic tube system, how is carrier direction reversed?

Accepted Answer

Reversing valves redirect blower airflow so it draws from the opposite end of the tube

Answer

A technician manually rotates the carrier 180 degrees at the sending station

Answer

Additional blowers at the destination push the carrier back toward the origin

Answer

The tube diameter is increased at midpoint to change flow characteristics

Question 6

What is the most likely effect of a significant air leak in a Casper pneumatic tube system?

Accepted Answer

The pressure differential decreases, causing slower or incomplete carrier transport

Answer

Carrier speed increases because turbulence adds propulsive energy

Answer

Only the blower motor temperature is affected, not carrier movement

Answer

The system self-compensates and performance is unaffected

Question 7

What is 'velocity pressure' (dynamic pressure) in the context of pneumatic tube airflow?

Accepted Answer

The pressure component associated with the kinetic energy of moving air

Answer

The manufacturer's maximum rated operating pressure for the tube

Answer

The additional pressure added by the carrier's own weight in the tube

Answer

The minimum blower pressure required to start a carrier moving from rest
