Water stream (density 992.9 kg/m3, viscosity 0.656 mPas) is fed to the shell side of a shell and tube heat exchanger. The inner diameter of the shell is 45 cm, it contains 79 tubes of diameter 25/30 mm. Linear velocity is 1.9 m/s. Calculate the Reynolds number. The correct answer is: 133999

solve it step by step until you get this number if your calculation is wrong I will report you if you put right number with wrong calculation
