QUESTION: 1

Solution:
QUESTION: 2

Solution:
QUESTION: 3

### Separators are generally used in air compressor installation

Solution:
QUESTION: 4

Which of the following is not true in the context of air receivers?

Solution:
QUESTION: 5

Identify the machine in which the fluid undergoes changes of pressure purely by dynamic effects

Solution:
QUESTION: 6

Which aspect is not true in the context of dynamic compressors as compared to positive displacement rotary compressors?

Solution:
QUESTION: 7

In a centrifugal compressor, the highest Mach number leading to shock wave in the fluid flow occurs at

Solution:

When the Mach number at impeller inlet radius exceeds unity, the air gets deflected through certain angle before its entry into the radial channel of the impeller vane. This leads to formation of shockwave which cause a rapid increase in the lossles.

QUESTION: 8

In a centrifugal compressor, the pressure rise per stage is restricted to

Solution:

Pressure ratio for centrifugal compressor = 4:1
Pressure ratio for axial flow compressor =1.2:1

QUESTION: 9

The application of centrifugal compressor leads to

Solution:

Centrifugal compressors have a large frontal area than that of an axial flow compressor of the same rating. This makes the axial flow compressor more suitable for aircraft work.

QUESTION: 10

The stagnation pressure rise in a centrifugal compressor stage takes place in the

Solution:

Pressure rise across centrifugal compressor
