Which of the following describes the orificemeter?

• A pipe has contra, throat and divergent portion

• A tunnel section with a large reservoir           

• A pipe has a circular plate with a hole inside it

• A large tank with a small hole at one of its ends

Two small circular orifice of diameters d₁ and d₂, respectively, are placed on the side of a tank at depths of 25 cm and 1 m below a consistently maintained surface of water. If the discharges through the orifices are the same, what is the ratio of the diameter d₁ to d₂

• 1/2

• 1/sqrt2

• 2

• sqrt2

A venturi meter is preferable to orifice meter because

• A)     it is cheaper

•      it is more convenien

•     energy loss is less

• A)     it is easy to assemble

For measuring flow in a venturimeter,it should be installed in

• Vertical line

• Horizontal line

• Inclined line with downward flow

• In any direction and in any location

The coefficient of discharge for an orifice meter is in the range

• 0.95 to 0.98

• 0.55 to 0.58

• 0.62 to 0.65

• 0.51 to 0.55

While using centrifugal pumps, if a head is to be developed, the impellers are connected in .

• high, series

• high, parallel

• low, series

• low, parallel
