2. Introduction • Fluid machinery • Fluid machine that adds energy to the fluid is called, pump, compressor, blower and fan. • Fluid machine that extracts energy from the fluid is called turbine.

3. Introduction • Fluid machinery • For fluid machines of dynamic type, the machines can be further divided according to the flow direction (respect to the rotating shaft) as • The radial flow machine: radial flow compressor, radial flow turbine. • The axial flow machine: axial flow compressor, axial flow turbine. • The mixed flow machine.

4. Introduction Gas Turbine Gas Turbine is usually referred to a unit consisted of compressor, combustion chamber and turbine. Gas Turbine convert heat energy of a fuel into mechanical energy.

14. Piston engine vs Gas turbine engine Advantages: Gas turbine engines have a great power-to-weight ratio compared to reciprocating engines. The flow of the fluid in the process can be classified as steady flow. Disadvantages: The main disadvantage of gas turbines is that, compared to a reciprocating engine of the same size, they are expensive, and they prefer a constant rather than a fluctuating load.
