Formula of Mass Flow Rate
The mass flow formula is given by,
m=ρVA
Where
ρ = density of fluid,
V = velocity of the liquid, and
A = area of cross-section
Solved Examples
Example 1
Determine the mass flow rate of a given fluid whose density is 800 kg/m3, velocity, and area of cross-section is 30 m/s and 20 cm2 respectively.
Solution:
Given values are,
ρ = 800 kg/m3
V = 30 m/s and
A = 20 cm2
= 0.20 m2
The mass flow rate formula is given by,
m = ρVA
m = 800 × 30 × 0.20
m = 4800 kg/s
