Question 1) Consider the tank described below. It is sealed on the left side, but the right-side tube is open to the atmosphere at a pressure P0=101kPa.L1=1m;L2=1.5m;L3=1m;L4=1m;L5=1.2m;A1=A3= 1m2;A2=A4=0.1m2;1=800kg/m3;2=8000kg/m3. What is the pressure, P[Pa], in the gas in the sealed part of the tank [Pa] ? (60,000pts)
