1 Two terms, transfer and transformation, are used while studying rotamachine. The former refers to the energy exchange between rotor and the fluid whereas the latter means change of form of energy such as pressure to kinetic energy.
2 Angular momentum is the moment of momentum about the axis of rotation.
3 Area of the flow in rotor blade row will increase, decrease, or remain the same depending on the type of machine and is discussed at appropriate place. While drawing Fig. 9.1.3, no consideration is given for it.
4 Head has different meaning in turbine and compressor and shall be discussed at the appropriate place later.
5 All liquids start changing their phase to vapour when they reach saturated liquid state. This depends on the ...
