A two Pass tube, baffled spacing single pass shell and tube HE is used to cool down hot methanol. cooling water flows thru tubes at 25C and a flow rate of 30 kg/sec. Methanol enters the shell at 90 C and should leave at 40C with 152kg/ sec. Perform a detailed deign of the exchanger to determine the surface area of this HE for a valid desigh where shell diameter between the range of (0.15, 0.25m) and the pressure drop across the exchanges both sides less than 0.75atm.

 

Counter Current, Triangular Pitch and Do= 23.2mm BWG= 16

 

 

Please HELP ME FIND AN EXCEL FILE THAT COULD DO ME THIS CALCULATION

 

As I am stuck in the hand calculation until finding the Friction Factor.

Thank you Breizh, Really Appreciate it, It helped but is there anyway I could find a spreadsheet that calculates the Pressure drops across the Shell side and the tube side of the HE??

An other resource but unfortunately no spreadsheet.

To me more important is the method .

 

Note : A good reference to have on your shelves : Process heat transfer by Kern

 

Good luck .
