An air pressure of 1,005 millibars is equivalent to approximately how many inches of Mercury?
N76 [4]

1005milibars of pressure corresponds to 29.68inches of mercury.

Option D.

<h3><u>Explanation:</u></h3>

Mercury has a density of around 13.6gm/cc. Thus the pressure of inches of mercury will have a huge effect on the value. As far as bar is concerned, it's around the normal atmospheric pressure measured at sea level. Its around 1,00,000 pascals. So from converting a pressure at millibars to inches of mercury, we need to divide the value by a factor of 33.864.

So, pressure in milibars =1005milibars.

So, pressure in inches of mercury = 1005/33.864 = 29.68 inches of mercury.
