Fluid flows in a heated pipe of the following dimensions: Length =5.2m, External Diameter =0.34m, Internal diameter = 0.25m, and pipe wall thickness 0.046m. You now need to calculate Re so that you can use it in correlation 8.60 in Table 8.4 : Re= Invalid element What is the value of the characteristic length in m ?
