Transportation and Metering Fluids

Question 1

this is applied in large lines such as city water system

Answer 1

venturi meter

Question 2

pitot tube measures the difference between the _______________ and ___________________

Answer 2

total pressure; static pressure

Question 3

this is expensive

Answer 3

venturi meter

Question 4

both of these measures flow rate

Answer 4

venturi and orifice meter

Question 5

this is usually inserted directly along the pipeline

Answer 5

venturi meter

Question 6

it is NOT the average velocity of the conduit/pipe

Answer 6

local velocity

Question 7

this measures the stagnation pressure at the stagnation point of the flow

Answer 7

pitot tube

Question 8

velocity at a specific location at a given point of the stream

Answer 8

local velocity

Question 9

A manometer (other device) is connected to two pressure taps shown and measures the pressure
difference in P1 and P2

Answer 9

venturi meter

Question 10

the flow rate is changed, thus inaccurate pressure difference readings

Answer 10

venturi meter

Question 11

this has fixed throat

Answer 11

venturi meter

Question 12

Used to measure fluid flow velocity specifically air and water

Answer 12

pitot tube

Question 13

this has high power loss

Answer 13

orifice meter

Question 14

one pipe diameter upstream and 0.3 to 0.8 diameter downstream

Answer 14

orifice meter

Question 15

it measures the difference between the total pressure and static pressure

Answer 15

pitot tube

Question 16

this needs considerable space

Answer 16

venturi meter
