4. One mole of helium gas is injected into each side of a slidable, airtight lead piston that separates two chambers of a sealed cylinder. The outside of the cylinder is insulated everywhere except where noted below. The cylinder and piston have lengths and cross- sectional area labeled in the diagram. The helium in the left chamber is heated from outside at a rate of 450 W, and the helium in the other chamber expels heat into a cool region. The full system eventually comes to steady-state. When it reaches steady state, the force needed to hold on the end cap is measured to be 18,000 N, and the piston has slid to an equilibrium point that is a distance à from the left end. force holding cap = 18,000N pressure. cross-sectional area of cylinder = 0.02m² x = ?

NOTE: Complete solution and show the derivation/cancellation of units. A steel flask of 0.04 m capacity is used to store Nitrogen at 120 bar and 20°C. The flask is protected against excessive pressure by a fusible plug which will melt and allow the gas to escape if the temperature is too high. A. How many kilogram of Nitrogen will the flask hold at the design conditions? B. At what temperature in °C must fusible plug melt in order to limit the pressure of flask to a maximum of 150 bar?
