Spiral wound channel

[finite]

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<br>
deep. The overall length of the drum is 3.6m. The drum rotates at 60m/min.<br>
<br>
I would like to know how to calculate the pressure drop of the heating fluid from inlet to exit of the drum<br>
<br>
Regards<br>

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