In a chemical processing system, the flow of glycerin at 60F (sg = 1.24) in a copper tube must remain laminar with a Reynolds number approximately equal to but not exceeding 300. Specify the smallest standard Type K copper tube that will carry a flow rate of 0.90 ft³/s. Then, for a flow of 0.90 ft³/s in the tube you specified, compute the pressure drop between two points 55.0 ft apart if the pipe is horizontal.
