A gas mixture consisting of 10% ethylene gas (C2H4) and 90% CO2 by mol is combusted with 50% excess air via the following unbalanced reaction: C2H4 (g) + O2 (g) à CO2 (g) + H2O (g) Air for the reaction is brought in from outdoors and cooled through a chiller to remove any humidity. The combustion product gas is pressurized so that all water vapor is condensed into liquid, which then combines with the water from the air chiller and exits through a separate H2O stream. a) Draw the process flow diagram. b) If the outdoor air has a dry bulb temperature of 30°C and 30% relative humidity (RH), how many mol of water leave the system (in the combined H2O exit stream) per mol of ethylene combusted? c) What is the molar volume (in L/mol) of the water-free combustion gas if it is pressurized to 150 atm at 20°C? CO2: Tc = 31.2°C, Pc = 72.8atm O2: Tc = -118.6°C, Pc = 49.8atm N2: Tc = -147°C, Pc = 33.5atm

One of the major concerns related to climate change is sea level rise. The Intergovernmental Panel on Climate Change (IPCC) has estimated that we are likely going to see sea level rise of around three feet by 2100. However, these estimates have come under heavy criticism in recent years as being far too conservative. Why are the IPCC estimates so conservative (i.e. what information does the IPCC not include in its models or estimates of sea level rise)? According to the VICE documentary piece that profiles Dr. Eric Rignot, how much would global sea levels rise if the West Antarctic Ice Sheet were to melt? (5%) How is Eric Rignot and his research team able to use radar and lasers to determine the thickness and melt rates of West Antarctic ice shelves?
