Centrifugal pump can't be used to pump _____________________?
Correct answer: D. Thick molten soap at 80°C
- A. Molten sodium (used as a coolant in Fast Breeder Reactor)
- B. Moderately viscous vegetable oil used in soap industry
- C. None of the above
- D. Thick molten soap at 80°C
Explanation
Centrifugal pumps are poorly suited to very viscous materials because viscosity causes large friction losses and reduces efficiency and capacity. Thick molten soap is therefore the unsuitable service among these choices.
