Water at 30C is being pumped through the annular area of a laboratory scale 1-pass, 1-shell tube exhanger with 4 tubes (galvanized iron) at a flow rate of 0.1m3/s. The inside diameter of the shell is 18.4cm while the outside diameter of each inner pipe is 2.7cm. The length of the system is 84.9m. The density and viscosity of water at 30C are 997.5kg/m3 and 0.000792Pa.s. The relative roughness of galvanized iron pipe is 1.5104m. Determine the Reynolds Number
