Bernoulli's Equation & Flow
GATE 2007
Medium
Match the items in columns I and II. Column I — P: Centrifugal compressor, Q: Centrifugal pump, R: Pelton wheel, S: Kaplan turbine. Column II — 1: Axial flow, 2: Surging, 3: Priming, 4: Pure impulse.
- P-2, Q-3, R-4, S-1
- BP-2, Q-3, R-1, S-4
- CP-3, Q-4, R-1, S-2
- DP-1, Q-2, R-3, S-4
Explanation
Centrifugal compressors are characterized by the instability known as surging (P-2); centrifugal pumps require priming before starting (Q-3); the Pelton wheel is the classic pure-impulse turbine (R-4); the Kaplan turbine is an axial-flow reaction turbine (S-1).
