Answer:
The pressure will be "0.579 psi".
Explanation:
The given value is:
Hg,
= 30 mm
Density of mercury (Pm),
= 13600 kg/m³
As we know,
1 psi = 6895 N/m²
Now,
The pressure will be:
= [tex]30 \ mm \ of \ Hg[/tex]
= [tex]30\times 10^{-3}\times Pm\times g[/tex]
On substituting the given values, we get
= [tex]30\times 10^{-3}\times 13600\times 9.8[/tex]
= [tex]3,998,400\times 10^{-3}[/tex]
= [tex]3,998.4 \ N/m^2[/tex]
So,
The pressure of 30 mm of Hg will be:
= [tex]\frac{3,998.4}{6895}[/tex]
= [tex]0.579 \ psi[/tex]
