A 20% ethylene glycol solution is flowing through a 4-nom sch 80 commercial steel pipe. The pipe is 350 ft long and is horizontal. The pressure drop through the pipe is 4 psi. The ethylene glycol is at a temperature of 20°F.

a. Determine the volumetric flow rate of the ethylene glycol (gpm)

b. Investigate the effect of the ethylene glycol temperature by plotting the volumetric flow rate (gpm) as a function of temperature for 20°F ≤ T ≤ 100°F.
