Fluid machinery is machinery that serves to transform mechanical energy into potential energy and vice versa. The fluid which is used can be water, steam, and gas.
Based on definition above, fluid machinery can be classified into two types as follow:
- Working machinery type which serves to transform mechanical energy into fluid energy, for example: pumps, blower, compressor, and others.
- Power machinery type that serves to convert fluid energy into mechanical energy such as water turbine, steam turbine, windmill, and others.
