1 + d/33 gives the pressure in the atmosphere at the depth of the sea.
the pressure at 40 feet is?
I did this yesterday.
1 + 40/33 = 1 + 1 7/33 = 2 7/33
which is about
2.21 atmospheres
To find the pressure at a certain depth in the sea, you can use the equation:
Pressure = 1 + d/33
Where "d" represents the depth in feet.
In this case, you want to find the pressure at a depth of 40 feet. Plugging in the value of "d":
Pressure = 1 + 40/33
Now, we can calculate the value of the expression:
Pressure = 1 + 1.2121
Adding the numbers together:
Pressure ≈ 2.2121
Therefore, the pressure at a depth of 40 feet in the sea is approximately 2.2121 atmospheres.
