1. Consider a natural gas stream that contains 95 vol% methane ($CH_4$), 4 vol% ethane ($C_2H_6$), and 1 vol% butane ($C_4H_{10}$) on a dry basis. a. What is the average molecular weight of this gas mixture (g/mol)? b. If this gas stream has a flow rate of 1000 L/min, what is the flow rate in $ft^3/s$? c. A sulphur species (a mercaptan) is added to natural gas so people can smell it in case of an accident. The mercaptan level is typically 5 ppm. What is this value in mol%? d. What information is required to calculate the amount (g) of mercaptan required per day for this natural gas stream, assuming the molecular weight of the mercaptan is 90 g/mol? Show the line calculation using a variable or variables for the missing information.
