Step 1:: Understand the problem
The question asks for the maximum depth a human can dive before being crushed by pressure. This involves understanding how pressure changes with depth and the human body's tolerance to pressure differences.
Step 2:: Review relevant concepts
The pressure underwater increases by approximately 1 atmosphere (atm) for every 10 meters of depth. The human body can withstand a pressure difference of about 6 atm before being crushed.
Step 3:: Calculate the maximum depth
Given that the surface pressure is 1 atm, we can calculate the maximum depth as follows: Maximum depth = (human body's tolerance to pressure difference - surface pressure) / pressure increase per 10 meters Maximum depth = (6 atm - 1 atm) / 1 atm/ 10m Maximum depth = 5 atm / 1 atm/ 10m Maximum depth = 50 m
Step 4:: Consider safety factors
In reality, divers should not dive up to the maximum tolerable depth due to safety concerns. A safety factor of around 2 is often applied, which means that the maximum diving depth should be half of the tolerable depth: Maximum diving depth = Maximum depth / 2 Maximum diving depth = 50 m / 2 Maximum diving depth = 25 m
Final Answer
Humans can dive up to a maximum depth of about 25 meters before being crushed by pressure, considering a safety factor of 2.
