Chapter 3.2 Notes . Rate in Fluids. Rates in fluid systems describe the motion of liquids and gases . Fluids in motion have speed and acceleration; however we use two different rates to describe how quickly fluids flow – volume flow rate and mass flow rate.

### Chapter 3.2 Notes

Rate in Fluids

• V represents the volume of fluid in a container.

• The volume flow rate is the change in volume per unit time.

• represents volume flow rate

• Equation for volume flow rate = change in volume / time

STOP! 16,800 gallons per minute and the tank can hold 143,000 gallons, how long can the shuttle supply oxygen?

Algebra Lesson

• The 16,800 gallons per minute and the tank can hold 143,000 gallons, how long can the shuttle supply oxygen?mass flow rate is the mass of fluid moved per unit time.

• represents the mass flow rate

• The equation for mass flow rate = change in mass/time

• Flowmeters depending on the measure the average flow rate of fluids by measuring pressure and velocity and calculating the flow rate.

• Flowmeters use indirect methods to measure flow rates so that they do not interrupt the flow.
