What is the pressure on a swimmer 10m below the surface of a lake? |
|
Answer» Solution :Here h=10M and `p=1000 kg m^-3` take `g=10 ms^-2` `P=P_a+pgh` `=1.01 times 10^5 Pa+1000 kg m^-3 times 10 ms^-2 times 10m` `approx 2 atm` This is a 100% increase in pressure from SURFACE LEVEL. At a depth of 1km, the increase in pressure is 100 atm Submarines are designed to withstand such ENORMOUS pressures. |
