1.1 A centrifugal delivers the following test results at a speed of $700\mathrm{r}/\min$. The fan is installed in a ducting system of system total pressure drop $p_{\text{syst }}=72Q^2$ with $p_{\text{syst }}$ in $\mathrm{Pa}$ and $\mathrm{Q}$ in $m^{3}s$. 1.1.1 Determine graphically what the flow rate in the system will be and the fan total pressure. 1.1.2 Determine what the flow rate will be if the rotational speed is increased to $800\mathrm{r}/\min$.
