Why Multi-Stage Compressor More Efficient Than A Single Stage Compressor?

two stage air compressor

The main reason for high efficiency of multi-stage compressor is the presence of intercooler. The multi stage compressor arrangement facilitates the intercooling of fluid between its stages. The intercooler may be water cooled or air cooled. It reduces the temperature of fluid to compress. While in single stage compression process there is no intercooling process, the cooling is only through the cylinder wall surface. This type of cooling is less efficient compared to intercooling.

Read: Single stage and Multi stage compressor - Advantages and Limitations

Single stage compressor
Multi-stage compressor
Only one cylinder for the compression process
More than one cylinder are connected in series
Used in low-pressure ratio application.
Achieve a very high-pressure ratio.
The size of cylinder is very large when compared to the cylinders in the multistage compressor.
Individual cylinders are small when compared to single cylinder compression.
The temperature of fluid due to compression is very high. No intercooler.
Temperature is low. Intercooling is more efficient than cooling with a cylinder wall surface. It also reduces thermal stress.

What is single stage compressor? What are the drawbacks/ limitation of single stage compressor?

When the compressor has only one cylinder, and it compresses the fluid in that cylinder then delivered at high pressure; it is called single stage compressor.

The following list describes the drawbacks of single stage compressor used for producing very high-pressure fluid.

What Is the Difference between Source Flow and Sink Flow?

What is source flow?

Source flow is defined as the two-dimensional flow coming from a point called source and moving out radially on a plane in a uniform rate. Fig.a represents a source flow. Here point O is the source. From source, fluid is flowing radially in all direction of plane. The strength of the source, q is defined as the volume flow rate per unit depth of fluid. The unit of source strength is m2/s.

Conditions Of Equilibrium Of Floating And Submerged Bodies

floating bodies equilibrium conditions

A floating or submerged body is said to be stable if it comes back to its original position after giving a slight disturbance. The condition of stability of these bodies depends on the position of its metacentre, centre of buoyancy and centre of gravity. The relationship between these points and the stability of body is described below.

Differentiate Centre Of Gravity, Centre Of Buoyancy And Metacentre?

Centre of gravity

Centre of gravity is an imaginary point at which the weight of body can be assumed to act. For a uniformly distributed mass, the centre of gravity will be same as the geometrical centre of that object. The concept of centre of gravity helps us to design of static objects, predict the behaviour of moving objects.
