I believe the first one is correct but please work out both problems. Thanks!

A source emission test reported a gas flow rate of 20,000 scfm (i.e., based on standard air temperature of 20C and pressure of 1 atm). The actual temperature, pressure, and water content of the gas are 100C, 1 atm, and 20% by volume, respectively. The gas flow rate, based on actual conditions of temperature and pressure, is most nearly 20,000 acfm 15,710 acfm 25,461 acfm none of the listed answer Question 2 1 pts A source emission test reported a gas flow rate of 20,000 scfm (i.e., based on standard air temperature of 20C and pressure of 1 atm).
