Answer 2

The low-pressure blower is a kind of compressible flow machine, therefore, option b is correct.

• The mechanism of a blower is to increase the pressure moderately to ease the movement of air or gas.
• We can change the direction of the application of pushing force on the air by the blower, by making changes to the blade angle of the blower.
• The compressible flow indicates the change in density of the fluid under consideration.
• On the other hand, incompressible flow indicates a flow in which the density of the fluid remains constant.
• In general the characteristic feature of water is incompressible, while that of a gas or air is compressible.
• Thus the low-pressure blower is a kind of compressible flow machine, therefore, option b is correct.
