Air flow calculator is used to find out the flow of air through particular device. It is an easy way to do the calculation. The equation of the air flow is given below.

q=$\frac{C_{v}\times 11\times \pi }{[SG(T+460)]^{\frac{1}{2}}}$

Where q is the air flow rate
$C_{v}$ is the flow coefficient
T is the gas temperature
SG is the specific gravity

## Steps on Air Flow Calculator

Step 1 :

Identify the given parameters from the question.

Step 2 :

Substitute all given values in the given equation, and find out the air flow.

q=$\frac{C_{v}\times 11\times \pi }{[SG(T+460)]^{\frac{1}{2}}}$

## Problems on Air Flow Calculator

1. ### Calculate the air flow whose flow coefficient is 0.5 and the gas temperature is 50F? SG is given as 1.

Step 1 :

The given values are,

Cv=0.5, T=50F and SG=1

Step 2 :

Air flow equation is given by,

q=$\frac{C_{v}\times 11\times \pi }{[SG(T+460)]^{\frac{1}{2}}}$

q=$\frac{0.5\times 11\times 3.14 }{[1(50+460)]^{\frac{1}{2}}}$

q=0.76472 ft3/m

Air flow, q=0.76472 ft3/m

2. ### Determine the air flow rate whose flow coefficient is 0.7 and the gas temperature is 80F? SG is given as 1.

Step 1 :

The given values are,

Cv=0.7, T=80F and SG=1

Step 2 :

q=$\frac{C_{v}\times 11\times \pi }{[SG(T+460)]^{\frac{1}{2}}}$

q=$\frac{0.7\times 11\times 3.14 }{[1(80+460)]^{\frac{1}{2}}}$

q=1.0404 ft3/m
