What is the difference between flow rate and velocity? Flow rate is the volume of fluid (e.g., water) that passes through a pipe or conduit per unit of time (e.g., GPM), while velocity is the speed of the fluid at a specific point in the pipe (e.g., feet per second).

Does flow rate change with pipe diameter? Flow rate can change with pipe diameter. In general, larger pipe diameters can accommodate higher flow rates with less friction and pressure drop, while smaller diameters restrict flow.

What is the relationship between pressure and flow rate in a pipe? The relationship between pressure and flow rate in a pipe is influenced by factors such as pipe diameter, fluid properties, and system design. In general, increasing pressure can lead to an increase in flow rate, but it’s not a linear relationship and depends on various factors.
