A beverage dispensing system consists of a bottle of beverage, a dispensing hose with valve, and a CO2 system to keep the beverage pressurized. The CO2 system includes a small bottle of high-pressure liquefied CO2 and a regulator to regulate the gas pressure delivery to the beverage. A typical beverage system contains a 9.27 gal beverage bottle, a 8.44 lb bottle of liquefied CO2 and a regulator set at 7.95 psig. The regulator is connected directly to the CO2 bottle, and a 0.47 in (internal diameter) plastic hose connects the regulator to the beverage bottle. The liquefied CO2 saturation vapor pressure is 1010 psia. Assume a temperature of 61°F. A pressure relief system must be designed to protect the beverage bottle from overpressure. The relief device will be installed in the CO2 line where it enters the beverage container. a. Draw a neat sketch showing the beverage dispensing system. Determine the vapor relief area. Write the equations with proper referencing. b. Determine the vent area required, assuming a set pressure of 16 psig and an overpressure of 10%. Assume suitable type of relief with justification
