# What is mass flow rate equation? Karim Khaled

Posted On: Apr 10, 2020

The mass flow rate is the mass of a liquid substance passing per unit time. In other words, the mass flow rate is defined as the rate of movement of liquid mass through a unit area. Here the mass of a substance that passes per unit of time. The mass flow is directly dependent on the density, velocity of the liquid and area of cross-section. It is the movement of mass per unit time. The mass flow is denoted by m and the units in kg/s. The mass flow rate equation is calculated by m=pVA, where p stands for a density of a liquid, v for velocity and A for an area of cross-section.

The formula for mass flow rate is given: Mass Flow Rate = (density)*(velocity)*(area of the cross section)
