Does anyone have a useful nemonic/memory technique for remembering the answers to questions such as:
"Turbine blade stages may be cassified as either impulse or reaction. In an impulse turbine stage:
A. The pressure rises across the stator bades and remains constant across the rotor blades;
B. The pressure remains constant across the stator blades and drops across the rotor blades;
C. The pressure drops across the stator blades and remains constant across the rotor blades;
D. The pressure remains constant across the stator blades and rises across the rotor baldes."
(answer in this example is C).
They are a real bugbear of mine...
Tks.
