What is the pressure at a depth of 80 m in the ocean? The density of seawater is 1. 03 × 10 3kg/m3. Please express your answer in units of atm.
Pressure=80m* 1.03*9.8 kPa+101.3kpa
now in terms of atmosphers, divide that all by 101.3kpa
To find the pressure at a given depth in the ocean, we can use the hydrostatic pressure formula:
Pressure = Density × Acceleration due to gravity × Depth
Given that the density of seawater is 1.03 × 10^3 kg/m^3, and the depth is 80 m, we need to know the acceleration due to gravity. Assuming it is approximately 9.8 m/s^2, we can calculate the pressure as follows:
Pressure = (1.03 × 10^3 kg/m^3) × (9.8 m/s^2) × (80 m)
Simplifying the expression:
Pressure = 80,240 N/m^2
To express the pressure in atm, we need to convert it from pascals (N/m^2) to atmospheres:
1 atm = 101,325 N/m^2
Therefore, the pressure at a depth of 80 m in the ocean is:
Pressure = 80,240 N/m^2 / (101,325 N/m^2/atm) = 0.792 atm
