what is the pressure dut to 30 m heght water column
Pressure at the bottom of a water column of height h = d*g*h
where, d=density of water(1000Kg/m^3)
g=9.8 m/s^2 & h=30 m
Calculate P yourself.
Atmospheric pressure should be added to Ajayb's answer.
To calculate the pressure due to a water column of a certain height, you can use the equation:
Pressure = Density x Gravity x Height
First, you need to know the density of water. The density of water at room temperature is approximately 1000 kg/m^3.
Secondly, the acceleration due to gravity is approximately 9.81 m/s^2.
Finally, the height of the water column is given as 30 m.
Using these values, you can calculate the pressure as follows:
Pressure = 1000 kg/m^3 x 9.81 m/s^2 x 30 m
Calculating this equation will give you the pressure in units of pascals (Pa).
