A marked departure from his previous book, the popular Portnoy's Complaint, Our Gang is a political satire written in the form of a closet drama. Centered on the character of "Trick E. Dixon", a caricature of then-President Richard Nixon , the book takes its cue from an actual quote from Nixon:
Where 1 to 3ss in Figure 1 represents the isentropic process beginning from stator inlet at 1 to rotor outlet at 3. And 2 to 3s is the isentropic process from rotor inlet at 2 to rotor outlet at 3. The velocity triangle [ 2 ] (Figure 2.) for the flow process within the stage represents the change in fluid velocity as it flows first in the ...

The Euler pump and turbine equations are the most fundamental equations in the field of turbomachinery. These equations govern the power, efficiencies and other factors that contribute to the design of turbomachines. With the help of these equations the head developed by a pump and the head utilised by a turbine can be easily determined.

In rotordynamical systems, the eigenfrequencies often depend on the rotation rates due to the induced gyroscopic effects or variable hydrodynamic conditions in fluid bearings.
A compressor map is a chart which shows the performance of a turbomachinery compressor. This type of compressor is used in gas turbine engines, for supercharging reciprocating engines and for industrial processes, where it is known as a dynamic compressor. A map is created from compressor rig test results or predicted by a special computer program.
Figure 1 shows head characteristics [1] of centrifugal pump versus flow coefficient. Within the normal operating range of this pump, 0.03 <Q/(ND 3 ) < 0.06 , the head characteristic curves approximately coincide for different values of speed (2500 <N<5000 rev/min) and little scatter appears may be due to the effect of Reynolds number.
