Question 1) As water passes from a pipe of larger diameter to apipe of smaller diameter in converging section, the staticpressure:

Becomes half

Increases

Decreases

Does not change

Question 2) The following reading have to be recorded from theflow measurement apparatus to calculate the mass flow rate from theventurimeter?

Pressures at the inlet and exit of the venturimeter

Pressures at the inlet and throat of the venturimeter

The rotameter reading venturimeter

The pressure at the throat and exit of the venturimeter

Question 3) If the flow rate of water increases, then thepressure drop in the venturimeter

increases

decreases

remains same

cannot say

Question 4) The pressure measuring instrument can directlyprovide electrical signals which could be used to collect datausing data acquisition systems and read on a PC

Bourdon Gauge

inclined manometer

Pressure Transducer

Vertical manometer

Question 5) How do you vary the flow rate through the fluid fowmeasurement experimental setup?

by increasing or decreasing the amount of water coliected in theweighing tank

by increasing or decreasing the time taken to collect the amountof water in the weighing tank

by varying the speed of the pump

by closing or opening the valve at the discharge section of theapparatus

Question 6) In the flow measurement experiment, consider usingthe weighing tank method for measuring the flowrate. If a 6 kg massis added to the weight hanger and it takes 60 seconds for theweight hanger to move up again, how much will be the calculatedflow rate? (show steps please)

1 kg/s

3 kg/s

0.3 kg/s

0.1 kg/s
