# What is Dimensional Formula of Rate of Flow?

Posted in Dimensional Formulae | Email This Post |Rate of flow is defined as the quantity of a fluid flowing per second through a section of a pipe or a channel.

Rate of flow is also known as Discharge Q.

Mathematically,

**Rate of flow = Volume / time**

Dimensional Formula of Volume = M^{0}L^{3}T^{0}.

Dimensional Formula of time = M^{0}L^{0}T^{1}.

Putting these values in above equation we get,

**Dimensional Formula of Rate of Flow= M ^{0}L^{3}T^{-1}.**

SI unit of Rate of flow is m^{3}s^{-1}

rate of flow is also known as discharge Q
