Pressure is force that acting on an object dividedby its area.Mathematically: P= Pressure ( N/m2 = Pascal) F P F= Force (N) A A= Surface Area (m2)
Hydrostatic pressure is the pressure exerted by a fluid atequilibrium due to the force of gravity.
Hydrostatic pressure can be calculated with theformula:Where:Ph = Hydrostatic pressure (Pa or N/m2)ρ = Density of liquid (kg/m3 )g = earth’s gravity (m/s2)h = Depth (m)
If the container is open so there is atmosphere pressure fromthe air to the surface of liquid…The pressure become: P0 = Atmospheric pressure (1 atm = 76 cmHg = 1.013 x 105 Pa) P = P0 + Ph = P0 + ρgh
A tube with height 50 cm filled with water. If thedensity of the water 1 gr/cm3 and the gravitationalforce is 10 m/s2 then the hydrostatic pressure in thebottom of the tube is….Calculating… Completed Calculate Known: ρ = 1 gr/cm3 = 1000 kg/m3 g = 10 m/s2 h = 50 cm = 0,5 m Asked: Ph....?
In the glass cylinder there are 20 cm oil. Withignoring the outside pressure, the pressure on thebottom of the cylinder is 1600 N/m2. What is thedensity of the oil?Calculating… Completed Calculate Known: Ph = 1600 N/m2 g = 10 m/s2 h = 20 cm = 0,2 m Asked: ρ....?
Thank you for the attention andparticipation to our presentation. Om Shanti,
