The exhaust system is correctly designed since the permissible total resistance of 30 mbar is not exceeded.
Density of air
Density of air can be determined by following
empiric, formula*:
* This formula is only valid between -20° to 60°C.
Example
At ambient air conditions 20°C and pressure 0.98
bar, the density is:
