Which of the following statements is not correct for the volumetric ef...
Explanation:
Volumetric efficiency is defined as the ratio of the actual volume of air delivered by the compressor to the swept volume of the compressor. It is expressed in percentage. The volumetric efficiency of a reciprocating air compressor depends on various factors such as delivery pressure, pressure ratio, clearance volume, and temperature.
The correct statement for the volumetric efficiency of a reciprocating air compressor is:
- It increases with a decrease in pressure ratio
- It increases with a decrease in clearance volume
- It decreases with an increase in ambient temperature
The incorrect statement is:
- It decreases with an increase in delivery pressure
This is because the volumetric efficiency of a reciprocating air compressor is inversely proportional to the delivery pressure. As the delivery pressure increases, the volumetric efficiency decreases. This is due to the fact that as the delivery pressure increases, the compression ratio also increases, which results in the decrease in the clearance volume. This, in turn, decreases the volumetric efficiency.
Therefore, the correct option is A) It decreases with an increase in delivery pressure.
Summary:
- Volumetric efficiency is the ratio of the actual volume of air delivered by the compressor to the swept volume of the compressor.
- The volumetric efficiency of a reciprocating air compressor depends on delivery pressure, pressure ratio, clearance volume, and temperature.
- The volumetric efficiency increases with a decrease in pressure ratio and clearance volume.
- The volumetric efficiency decreases with an increase in ambient temperature and delivery pressure.
- The incorrect statement is that the volumetric efficiency increases with an increase in delivery pressure.
