Cubic area of space to be cooled = 2.43 × 2.43 × 3.04

= 17.95 m³

30 L/s = 0.03 m³/s

To maintain 22°C, the space gets changed every:

= 17.95 m³ / 0.03 m³/s

= 598 s

** From here, I don't know what to do. I know there is a relationship between flow rate and temperature but I can't figure it out**

*The formulas they give us are just the basic flow rate equations with no variable being temperature, therefore I am assuming that this question can be figured out using proportions, but I have no idea how to proceed**

**Summary:**Calculate the air change rate required to keep a certain temperature**In question d above, you were asked to calculate how long the air flow in the system would be active in a day. Now factor in the following to address temperature readings and flow requirements. The occupant desires the temperature in the space to be a constant 22°C. When the air flow is at 30 litres per second, this is maintained. The outside air temperature today is 10°C and the air temperature through the system is 24°C. How often will the system need to change the air in the 2.43 metre wide by 3.04 metre long and 2.43 metre high cubicle to meet the desired temperature?**Cubic area of space to be cooled = 2.43 × 2.43 × 3.04
