Compressor fundamentals: select the correct statement among the following. Evaluate each statement about definitions and work in air compression, and choose the only correct one.
Clearance volume and volumetric efficiency in compressors: validate the statement for design practice. Statement to evaluate: Clearance volume is kept as small as possible because it adversely affects volumetric efficiency. Choose whether the statement is correct.

Pressure rise mechanism in a sliding vane blower: evaluate the two-stage explanation. Statement to evaluate: In a vane blower, the pressure increases first due to internal compression (decreasing cell volume) and then due to some backflow from the discharge until line pressure is reached.
