Why does discharge pressure increase at the outlet of a reciprocating compressor?

Question

Accepted Answer

Discharge pressure increases at the outlet of a reciprocating compressor due to compression of the gas.

During the compression process, the gas molecules are forced into a smaller volume, resulting in an increase in pressure.
The reciprocating motion of the compressor piston compresses the gas in the cylinder, leading to an increase in pressure.
The discharge valve of the compressor prevents the compressed gas from flowing back into the cylinder, causing the pressure to build up at the outlet.
Factors such as the compression ratio, cylinder size, and speed of the compressor also affect the discharge pressure.
Higher discharge pressure is desirable for applications that require high-pressure gas, such as in industrial processes or air conditioning systems.
