what is the si unit of pressure? how is it related to pressure in atmosphere?
The SI units of pressure is Pascal (Pa). It is such that
1 Pa = 1 N/m2
now, the relation between atmospheric pressure and unit of pressure is
1 atm = 101325 Pa ~ 105 Pa
Define pressure and how it is related to force and area and give it's SI unit also.
The normal atmospheric pressure is 76 CM of mercury. Calculate the pressure in SI units. Density of Hg = 13600 kg/m3 g =10
