Underwater remotely operated vehicles are used to check underwater pipelines and structures such as gas platforms. They have operating depths from 150 to 300m. Calculate the pressure these vehicles are experiencing at this depth in Pascals (Pa) and in atmospheres (atm).
Compare this pressure to the air pressure supplied to a car lift capable of lifting a 1357kg sedan. The piston under the car has an internal diameter of 30cm while the smaller piston at the pressurised gas supply has an internal diameter of 10cm.
