Question

In _________pumps, the energy of the fluid is converted into velocity energy.

(a) positive displacement

(b) jet

(c) airlift

(d) propeller pumps

I had been asked this question in class test.

I would like to ask this question from Fluid Flow Applications in division Fluid Flow Theory & Applications of Food Processing Unit Operations

Answer 1

Correct answer is (b) jet

To explain: In jet pumps, a high velocity jet is produced in a nozzle where the energy of the fluid is converted into velocity energy. Jet pumps have low efficiencies but they have no moving parts and therefore have low initial costs.
