9. Figure 3-8 shows a system arranged to maintain the pressure inside the vessel at a specified pressure, no matter what temperatures the gas may reach. Initially the vessel is filled to the prescribed pressure, but as the tem- perature changes, the pressure in the vessel may change according to Ex- periment 2. The constant pressure valve at the top either opens or closes to maintain the original pressure a. If the temperature increases by 15% how does the valve correct for the change in pressure? What percent of the original air is lost? b. If the temperature increases by 25% what does the valve do and how much air is involved? Figure 3-8 Pressure relief valve
