Q1. Answer : ( c )
Any type of pump comes under the category of open system and fixed volume or control volume also mean the open system . So a positive displacement pump will eject a fixed volume of the fluid .
NOTE : Fixed mass or control mass means closed system .
Add Answer to:
1. A positive displacement pump has the following characteristic(s) (a) It pumps a certain quantity of...

A centrifugal pump is used to pump water at 77ºF from a reservoir whose surface is 20 ft above the centerline of the pump inlet. The Pipe System consists of 67.5 ft of PVC pipe with a 1.2 in ID and negligible average internal roughness height. The length of the pipe from the bottom of the lower tank to the pump inlet is 12 ft. There are several minor losses in the pipe: an acute edge entry (KL = 0.5),...
