Max Depth of Submarine Modeling: 80kpa

AI Thread Summary
To model the maximum depth a submarine can reach under a pressure of 80 kPa, it's essential to understand hydrostatic pressure, which increases with depth. The pressure at a given depth can be calculated using the formula P = ρgh, where ρ is the density of water, g is the acceleration due to gravity, and h is the depth. Since 1 meter of water corresponds to approximately 10 kPa, a maximum pressure of 80 kPa allows for a depth of about 8 meters. Integrals are not necessary for this calculation, as the relationship is straightforward. Understanding these principles will help in formulating the required equation for the project.

Hello, I'm working on a project, and my teacher gave me something to think about, but I am at a loss. He wants me to come up with an equation to model the maximum height a submarine can go underwater, if it can withstand a maximum pressure of 80kpa. I started thinking it was an integral problem, integ(dP/dz) but I'm not sure. Any help would be much appreciated.

How does hydrostatic pressure depend on depth? (It's simpler than you think.)
 
it would be very cool if you solve that with integrals, but its a lot more than you need, really
 
What they said. No integrals required.

1m head of water = 0.1bar = 10kpa
 
Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (First part)'
I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8 and stuck at some statements. It's little bit confused. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. Solution : The surface bound charge on the ##xy## plane is of opposite sign to ##q##, so the force will be...
