Volumetric flowmeters work by :

alternatively filling and draining chambers inside them

all answers are correct

displacing a certain number of liquid volumes per unit time

Convert 9 gallons per minutes to cubic meters per day.

Knowing that :

1 FT³ = 7.48 gallons

1 m³ = 1000 liters

1 gallon = 3.78 liters

Make sure the answer is rounded to two significant digits after the decimal point
