Question

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

Becomes half

Increases

Decreases

Does not change

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

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 the pressure drop in the venturimeter

increases

decreases

remains same

cannot say

Question 4) The pressure measuring instrument can directly provide electrical signals which could be used to collect data using 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 fow measurement experimental setup?

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

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

by varying the speed of the pump

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

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

1 kg/s

3 kg/s

0.3 kg/s

0.1 kg/s
