#5
Which term refers to the force per unit area exerted by a fluid on its container walls?
Pressure
ExplanationMeasure of force distributed over a fluid's area.
#6
Which type of pump is commonly used for transferring liquids in a steady flow?
Centrifugal pump
ExplanationGenerates flow by accelerating liquid radially outward.
#7
Which of the following materials is commonly used for manufacturing flexible hoses in fluid transfer systems?
