What would be the height of the column in a barometer if the external pressure was 101kpa and water (d=1.00g/cm^3) was used in place of mercury ??
a)0.0558m
b)0.760m
c)1.03×10^4m
d)10.3m
e)0.103m

Answer : The height of the column in a barometer is, 10.3 m

Explanation :

To calculate the height of the column in a barometer we are using formula as:

where,

P = external pressure =

Conversion used :

h = height of the column in a barometer = ?

= density of water =

Conversion used :

g = constant of gravity =

Now put all the given values in the above formula, we get:

Therefore, the height of the column in a barometer is, 10.3 m

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
