Same pumping power
-
The present work showed that the highest thermal performance factor under the same pumping power obtained from the experiments, is about 2.26 times more than that of plain duct.

CHAPTER 11 PNEUMATIC AND HYDRAULIC MACHINE AND MECHANISM CONTROL DESIGNS AND OPERATING PRINCIPLES OF TYPICAL PUMPS These pumps are used to transfer liquids and supply hydraulic power. 1. WITH BUT TWO MOVING PARTS, the rotors that turn in the same direction, this rotary pump has reduced friction to a minimum. The rotors rotate against flexible synthetic rubber cushions that allow sand, grit and other abrasives to flow freely through the pump without damage. It is a positive displacement pump that develops a constant pressure and will deliver a uniform flow at any given speed.
