Spiral wound channel
Spiral wound channel
(OP)
I have a heating drum used to to heat PVC sheet.The drum has a diameter of 600mm. A spiral channel is inside the roller to provide good heat transfer from the heating fluid to the PVC sheet.The size of the channel is 30mm wide x 12mm
deep. The overall length of the drum is 3.6m. The drum rotates at 60m/min.
I would like to know how to calculate the pressure drop of the heating fluid from inlet to exit of the drum
Regards

RE: Spiral wound channel
Pressure drop or delta P, depends on the fluid flow ( in GPM ) ,Friction factor, Density and lenth. If you look at any
good fluid power hand book the formula should be their.
I have it, but can't type it accurately.
Ofcorse, you can always put a gauge or transducer on the inlet and out let to measure the delta P.
