A water tank is20m deep if the water barometer reads10m at that place then what is the pressure at the bottom of the tank in atmosphere
done already
To determine the pressure at the bottom of the water tank, we can use the formula for pressure:
Pressure = Density × Gravity × Depth
Here's how you can calculate the pressure:
1. Find the density of water: The density of water is approximately 1000 kg/m^3.
2. Determine the acceleration due to gravity: On Earth, the standard value for gravity is 9.8 m/s^2.
3. Calculate the depth from the surface to the bottom of the tank: In this case, the depth is given as 20m.
Now, we can plug in the values into the formula:
Pressure = 1000 kg/m^3 × 9.8 m/s^2 × 20m
After performing the calculation, we get:
Pressure = 196,000 Pascal
Note that Pascal is the SI unit for pressure. To convert this pressure into atmospheres, we need to divide the value by the atmospheric pressure at sea level, which is approximately 101,325 Pascal.
Therefore:
Pressure in atmospheres = 196,000 Pascal / 101,325 Pascal
After dividing, we find:
Pressure in atmospheres ≈ 1.93 atmospheres
So, the pressure at the bottom of the water tank is approximately 1.93 atmospheres.
