The pressure of the atmosphere according to the weather report is Kpa is 4851.568 Kpa.
The weather report give the atmospheric pressure to be 31.5 in of mercury.
Converting 31.5 inch into cm,
The height of mercury column is 80.01 cm.
We know, the pressure given by the mercury column is given by,
P = pgH
Where,
p is the density of mercury,
g is the acceleration due to gravity,
H is the height of the mercury column.
So, putting values,
P = 80.01 x 136000 x 80.01/100
P = 4851568 pa.
So, the pressure of the atmosphere according to the weather report is 4851.568 Kpa.
