Define mass and volume flow rates. How are they related to each other?
Anettt [7]

Answer:

The mass of a substance that passes per unit of time is called the mass flow rate, the unit of mass flow rate is kilogram per second in SI units.

\rho=\frac{\dot{M}}{\dot{V}}

Step-by-step explanation:

Consider the provided information.

We need to Define mass and volume flow rates and how they are related.

The mass of a substance that passes per unit of time is called the mass flow rate, the unit of mass flow rate is kilogram per second in SI units.

The volume of fluid which passes per unit time is called volume flow rate.

The relation between them is:

The Mass flow rate = Density × Volume flow rate

Or

\rho=\frac{\dot{M}}{\dot{V}}

Where ρ is the density.
