The concentration of a gas in a room is given by,
C = [L/(V x n)] x 100
Where, C = gas concentration (%); L = gas release (cfm); V = room volume (ft3); n = air changes per minute
here L = 4.73 cfm
V x n = 1500 cfm
C = (4.73/1500) x 100 = 0.315%
The final concentration of toluene in the room is 0.315%

Your house is located in a polluted city with an ambient ozone concentration of 80 ppb by mole (exceeding the NAAQS!). The air intake into your house has a flow of 1500 L/min of air, which is the same as the outflow rate. Ozone is very reactive, and will oxidize chemicals (mostly at the surfaces of your house) such as the oils on the walls or on people’s skin. At steady state, if the indoor concentration of ozone in your...

S-4. In the indoor air of the room described in S-3 above, nitrogen dioxide (NO2) is continuously released from a combustion source and destroyed by photochemical reactions, at a constant rate of 40 μg/min. The steady state concentration of NO2 in this room is measured to be 20 μg/m3. Calculate its residence time.

a. Calculate the dry air and water vapor mass flow rates (lb/min) if the volume flow rate is 1,000 cfm, the humidity ratio is 0.025 lbv/lba, and the dry air density is 0.072 Iba/ft3. b. Assume the above air enters an evaporator coil at 90°F where it is cooled in a constant humidity ratio process until reaching the 100 % RH curve ( the temperature at that point is the dew point. The air then keeps dropping in temperature, following...

A compressor at steady state uses R22 at a saturated vapor of 4 bar. If the process occurs adiabatically and reversibly, and it compresses the fluid to 18 bar, what is the required mass flow rate of the refrigerant in kg/s if the power required for the compressor is 7.5 kW. State assumptions used in order to make this calculation and draw a T-s diagram. Show all work.
