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.

Methods for measuring volume and mass flow rates vary, depending on the situation.
The simplest, most direct method to find average flow rate is to collect fluid and measure the amount of fluid collected over time.

Flowmeters 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.

Volume flow rate equation using speed = area x speed
Mass flow rate equation using speed = density x area x speed
To find cross sectional area of a pipe use this equation = pi x r2
