The 60W fan of a central heating system is to circulate air through the ducts. The analysis of the flow shows that the fan needs to raise the pressure of the air by 50Pa to maintain flow. The fan is located in a horizontal flow section whose diameter is 30cm at both inlet and outlet. Determine the highest possible average flow velocity in the duct.
