An insulated vessel contains 1.5 moles of argon at 2 atm. the gas initially occupies a volume of 5 l. as a result of the adiabatic expansion the pressure of the gas is reduced to 1 atm. (a) find the volume and temperature of the final state. (b) find the temperature of the gas in the initial state. (c) find the work done by the gas in the process. (d) find the change in the internal energy of the gas in the process.

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.
