Question

A pitot tube is inserted in an air flow at 20 C . The dashed lines represent mercury with a specific gravity of 13.6. If delta h was measured to be 30 mm. determine the speed of air flow?Use Cp=1.0

Expert Solution

Step 1

Given:

The height difference is: $∆ h = 30 mm$ .
The specific gravity of the mercury is: $S G_{Hg} = 13.6$ .
The coefficient of the pitot tube is: $C_{P} = 1.0$

Determine the density of the mercury.

$ρ_{Hg} = ρ_{w} \times S G_{Hg}$

Here,

The density of the water is $ρ_{w}$ and its value is $ρ_{w} = 1000 kg / m^{3}$ .

Substitute all the known values in the above equation.

$\begin{array}{rcl} ρ_{Hg} & = & 1000 \frac{kg}{m^{3}} \times 13.6 \\ = & 13600 \frac{kg}{m^{3}} \end{array}$
