a drum has height of 5 meters filled with water and open to atmosphere. compute for pressure acting st the middle of the drum.
To compute the pressure acting at the middle of the drum, we can use the concept of hydrostatic pressure. The hydrostatic pressure is given by the equation:
P = ρgh
Where:
P is the pressure
ρ is the density of the fluid (in this case, water)
g is the acceleration due to gravity
h is the height of the fluid column
First, we need to determine the density of water. The density of water is approximately 1000 kg/m^3.
Next, we need to calculate the height of the fluid column. Since the drum has a height of 5 meters and is open to the atmosphere, the height of the fluid column will be half the height of the drum, which is 2.5 meters (5 meters / 2).
Substituting the values into the equation, we have:
P = (1000 kg/m^3) * (9.8 m/s^2) * (2.5 m)
Calculating the equation will give us the pressure acting at the middle of the drum.
