Answer to Question #200050 in General Chemistry for sarah

Question

As a chemical engineer you need to pump the products without affecting products properties.

Because the flow properties will affect the fluid properties of the products like density and

viscosity. Pumping without destroying product integrity is as important as the heat

exchanger that comes after the pump. The piston pumps can handle very delicate and

viscous food stuffs and can pump up to very high pressure without damaging the food

particles. It can also be applied very successfully in heavy duty applications for industries

other than the food industry.

Answer the following

Pump Can work empty (without product)

1.• Allows high pressure drop (20 bar)

2-• Can work under vacuum

3-• Is self-priming

Answer 1

• Is self-priming

Therefore, if the pump is not primed, the suction pressure created will not be sufficient to lift water. Whereas in Positive Displacement Pump, during suction phase, piston moves backward and form a low pressure zone in the pump.
