Question

Consider an operation that applies mechanical work to transport liquid water while increasing its pressure. Choose a device you need.  (5 points)

	A.	Pump
	B.	Nozzle
	C.	Turbine
	D.	Compressor

Answer 1

For a operation that applies mechanical work to transport liquid water while increasing its pressure, we require "pump" Because pump is normally used for liquids only that required mechanical work and it increases the pressure of the liquid.

For nozzle there is no need of work and it decrease the pressure and increase velocity or kinetic energy of fluid.

Turbine is a work producing unit. There is no requirement of mechanical work.

While Compressors are used for the gases only. And water also is a incompressible fluid.

So the answer is "PUMP".
