You are in an old spy movie and have been locked into a small room (volume 1,000 ft3). You suddenly realize that a poison gas has just started entering the room through a ventilation duct and that the poisonous air is not leaving the room. What is the correct formula for mass conservation? you are safe as long as the concentration is less than 100 mg/m3. If the ventilation airflow rate in the room is 100 ft3/min and the incoming gas concentration is 200 mg/m3, how long do you have to escape? (in minutes)

A tank contains 49 gallons of a solution composed of 85% water and 15% alcohol. A second solution containing half water and half alcohol is added to the tank at the rate of 4 gallons per minutes. At the same time, the tank is being drained at the same rate. Assuming that the solution is stirred constantly, how much alcohol will be in tank after 10minutes?
You are in an old spy movie, and have been locked into a small room (volume 1000 ft). You suddenly realize that a poison gas has just started entering the room through a ventilation duct. Recognizing the type of poison from its smell, you know that if the gas reaches a concentration of 100 mg/m, you will die instantly, but that you are safe as long as the concentration is less than 100 mg/m. If the ventilation air flow rate in the room is 100 ft/min and the incoming gas concentration is 200 mg/m, how long do you have to escape?
Natural gas is stored in a spherical tank at a temperature of 10°C. At a given initial time, the pressure in the tank is 100 kPa gage, and the atmospheric pressure is 100 kPa absolute. Sometime later, after considerably more gas is pumped into the tank, the pressure in the tank is 200 kPa gage, and the temperature is still 10°C. What will be the ratio of the mass of natural gas in the tank when p = 200 kPa gage to that when the pressure was 100 kPa gage? 8. At a temperature of 100°C and an absolute pressure of 5 atmospheres, what is the ratio of the density of water to the density of air, ρw/ρa?
The reading of an automobile fuel gage is proportional to the gage pressure at the bottom of the tank.
