Question

What is the height of a fluid column in a barometer that uses water as its fluid in 0.810 atm of air pressure? The density of water is 1000 kg/m3. Neglect the vapor pressure in the apparently empty space above the column. Use ????=9.80 m/s2 and give the height in meters.

Answer 1

8.735 meters is the height of a fluid column in a barometer.

Step-by-step explanation:

`P=\rho * g* h`

Where:

P = pressure of the fluid at h height of depth

`\rho` = Density of the fluid

g = acceleration due to gravity

According to question weh ave ;

P =0.810 atm = 0.810 ×101325 Pa = 82,073.25 Pa

(1 atm=101325 pa)

h = ?

g =
`9.8 m/s^2`

`\rho =1000 kg/m^3`

`h=(p)/(\rho g)=(82,073.25 Pa)/(1000 kg/m^3* 9.8 m/s^2)`

`h=8.375 m`

8.735 meters is the height of a fluid column in a barometer.
