In Problem above, find the depth at which the net force on the tank is zero.
Problem :-
On a certain day the barometric pressure at sea level is 30.1 in. Hg, and the temperature is 708F.
The pressure gage in an airplane in flight indicates a pressure of 10.6 psia, and the temperature gage shows the air temperature to be 468F. Estimate as accurately as possible the altitude of the airplane above sea level.
