## Mass Flow Rate Formula :

The mass flow formula is M_{(kg/s)} in kilogram per second is equal to the product of density of fluid ρ _{(kg/m3)} in kilogram meter^{3} and multiply the velocity V _{(m/s)} in meter per second and multiply the area of cross section A_{(cm2)} in centimeter^{2} .Hence the mass of flow rate can be written as,

**M _{(kg/s)}=ρ _{(kg/m3)}*V _{(m/s)}*A_{(cm2)}**

Where,

ρ→ density of fluid in kilogram cube meter

V→ velocity in m/s

A→ area of cross-section in centimeter^{2}

## Sample Sums :

### Sum1 :

Calculate the mass flow rate of a given fluid whose density is 500kg/m^{3}, velocity, and area of cross-section is 40m/s and30Cm^{2} respectively.

### Solution :

Given values are

ρ =500Kg/m ^{3}

V=40m/s amd

A=30 cm^{2}

=0.30 m^{2}

The mass flow rate formula is given by

m=ρVA

m=500 *40 *0.30

m=6000kg/s

### Sum2 :

Calculate the mass flow rate of a given fluid whose density is 800kg/m^{3}, velocity, and area of cross-section is 30m/s and 60Cm^{2} respectively.

### Solution :

Given values are

ρ =800Kg/m ^{3}

V=30m/s amd

A=60 cm^{2}

=0.60 m^{2}

The mass flow rate formula is given by

m=ρVA

m=800 *30 *0.60

m=14400kg/s
