In a particular section of a fluid system, a 30% ethylene glycol mixture is flowing through a 6-nom xs cast iron pipe at a temperature of 0°C. In this section of piping, the velocity must be maintained in the range 1.5 m/s < V < 1.8 m/s. Determine the following,

a. The range of volume flow rates corresponding to the velocity limits (L/s)

b. The range of friction factors corresponding to the velocity limits
