A shell and tube type of heat exchanger with one shell pass andtwo tube passes will be designed to provide the given heat transferrate Q(kW) to cool hot water by using cold river water . The hotwater flows through the shell and the cold water flows through thetubes. The inlet and outlet temperatures of the hot water and thecold water are given as Thi, The and Tci, Tce in degrees Celcius.Design the shell and tube heat exchanger by making necessaryassumptions to calculate the dimensions of the heat exchanger. Q=10 KW Hot Fluid( Water) Thi= 70 Celcius The= 40 Celcius Cold Fluid( Water) Tci= 5 Celcius Tce= 15 Celcius 1) Assume the tube diameterand tube length . 2) Assume fouling coefficient based on inside andoutside tubes, hdi and hdo . 3) Select the material of constructionfor the tubes to determine the thermal coefficient. 4) Find the LogMean Temperature Difference (LMTD) . 5) Obtain the CorrectionFactor F. 6) Calculate the Mean Temperature Difference. 7) Assumethe Overall Heat Transfer Coefficient “U” as initial guessaccording to type of heat exchanger. 8) Calculate the provisionalarea. 9) Calculate the number of tubes based on the assumed tubediameter, thickness of the pipe and tube length L. 10) Calculatethe tube pitch and bundle diameter. 11) Obtain the bundle diameterclearence. 12) Select the minimum Shell thickness according tonominal shell diameter. 13) Calculate the shell inside diameter 14)Calculate the baffle spacing. 15) Calculate the area for cross flowfor the hypothetical row of tubes at the shell equator ( at theshell diameter plane). 16) Calculate the shell side mass flowvelocity. 17) Calculate the shell side equivalent diameter (hydraulic diameter) 18) Calculate the shell side Reynolds number.19) Calculate or obtain the Prandtl number. 20) Calculate the shellside heat transfer coefficient. 21) Read the friction factor fromJf tablet for the calculated Shell side Reynolds number in order tocalculate the shell side pressure drop. 22) Calculate the number oftubes per pass. 23) Calculate the tube-side mass velocity. 24)Calculate the tube-side velocity. 25) Calculate the Prandtl andReynolds numbers for fluids inside the tubes. 26) Calculate theheat transfer coefficient hi. 27) Calculate the overall heattransfer coefficient “U”. 28) Compare the calculated “U” with thatassumed in step 7).
