How do you classify an air compressor based on discharge pressure?

Classification of Compressor on basis of Discharge Pressure: 1 bar = 10 5 Pa = 1.01972 kgf/cm 2 Air flows steadily at the rate of 1 kg/s through an air compressor at 10 m/s, 100 kPa and 1 m 3 /kg and leaving at 6 m/s, 800 kPa and 0.2 m 3 /kg. The internal energy of the air leaving is 100 kJ/kg greater than the air entering.

How fast does air flow through a compressor?

Air flows steadily at the rate of 1 kg/s through an air compressor at 10 m/s, 100 kPa and 1 m 3 /kg and leaving at 6 m/s, 800 kPa and 0.2 m 3 /kg. The internal energy of the air leaving is 100 kJ/kg greater than the air entering. Cooling water in the compressor jacket absorbs heat from air at the rate of 100 kW. Find the rate of work done. Concept:

What is the compression process for uncooled rotary compressor?

The compression process for uncooled rotary compressor is Explanation: An uncooled rotary compressor is a type of compressor that is commonly used in air conditioning and refrigeration systems. It is called an "uncooled" compressor because it does not use a cooling mechanism to remove the heat generated during the compression process.

What happens if a compressor has a low flow rate?

At low flow rates, the velocity and pressure conditions within the compressor may deviate significantly from the designed parameters, causing a mismatch between the impeller (which accelerates the air) and the diffuser (which slows down and increases the pressure of the air).
