At what depth in water is the pressure equal to 2m atmosphere.
Explain how
Explain what you mean by "2m atmosphere".
2 atmosphere is a pressure; 2m atmosphere is not.
You also need to specify if you want the absolute or the gauge pressure.
Thats wer my confusion is Dr Bob the question is just like that in an assignment i don't understand it
Sorry about the name dr wls
To determine the depth at which the pressure is equal to 2 atmospheres (2 atm) in water, you need to understand the concept of hydrostatic pressure.
Hydrostatic pressure is the pressure exerted by a fluid at rest due to the weight of the fluid above it. The hydrostatic pressure in a fluid increases with depth. In a column of fluid, each vertical unit of depth adds a certain amount of pressure.
To calculate the hydrostatic pressure at a specific depth in water, you can use the formula:
P = ρgh
Where:
P is the hydrostatic pressure,
ρ (rho) is the density of the fluid,
g is the acceleration due to gravity, and
h is the depth.
In this case, we want to find the depth at which the pressure is equal to 2 atm. Standard atmospheric pressure at sea level is approximately 1 atm.
First, we need to convert 2 atm into the corresponding pressure in pascals (Pa), as the formula uses SI units. 1 atm is approximately equal to 101,325 Pa. Therefore, 2 atm is equal to 2 x 101,325 Pa, or 202,650 Pa.
For water, the density (ρ) is approximately 1000 kg/m^3, and the acceleration due to gravity (g) is approximately 9.8 m/s^2.
With these values, we can rearrange the formula to solve for the depth (h):
h = P / (ρg)
Substituting the values, we have:
h = 202,650 Pa / (1000 kg/m^3 * 9.8 m/s^2)
Simplifying the equation:
h ≈ 20.66 meters
Therefore, at a depth of approximately 20.66 meters in water, the pressure would be equal to 2 atmospheres.
