Bernoulli's Equation & Flow
GATE 2017
Easy
Which one of the following is NOT a rotating machine?
- ACentrifugal pump
- BGear pump
- Jet pump
- DVane pump
Explanation
A jet pump has no moving/rotating parts — it entrains and pumps fluid purely by momentum exchange with a high-velocity driving jet through a fixed nozzle. Centrifugal, gear, and vane pumps all rely on a rotating impeller, gears, or vanes.
