This is an old exam practice question. The answer is Pmax = 218.8 kN normal stress governs but why?
Moist air initially at T₁ = 140°C, p₁ = 4 bar, and p₁ = 50% is contained in a 2.0-m³ closed, rigid tank. The tank contents are cooled to T₂
35°C.
Step 1
Determine the temperature at which condensation begins, in °C.
Air at T₁ = 24°C, p₁ = 1 bar, 50% relative humidity enters an insulated chamber operating at steady state with a mass flow rate of 3
kg/min and mixes with a saturated moist air stream entering at T2=7°C, p₂ = 1 bar. A single mixed stream exits at T3-17°C, p3=1 bar.
Neglect kinetic and potential energy effects
