Hi there,(adsbygoogle = window.adsbygoogle || []).push({});

I am not an engineer but i do have scientific background. It is just a long time since i did any calculations!

I am trying to design myself a new way of melting barrels of honey. I have 200L, 300kg barrels of crystalized honey that I need to melt. One method I envisage is to make an 'element' type coil of pipe with hot water flowing though it that would melt the honey in the barrel from the inside out.

How would I calculate the surface area that the element would need to be to melt a barrel of honey in say 24 hours?

That is from 10C to 50C. with say the water at 60C.

Ah yes the specific heat capacity of honey is 0.73cal/g/C.

Could i also work out how much hot water i needed? and how fast i would need to pump it around the coil?

How do you think this would compare to just sitting the barrels in a big vat of hot water?

Thanks for your help. It is much appreciated.
