Hi everyone:

I need your brain on how to design a concrete slab: Below are parameters to be use/consider.

Concrete Slab length 30800mm
Concrete Slab width 11850mm
Concrete slab thickness 300mm

Glycol tubing runned at 75mm below surface of this slab will be used to circulate heated glycol at 200F to maintain a temperature of 41F at the surface of the slab when the ambient temperature is -40F during winter month (i.e heat will be transferred through the tubing and concrete slab to the surface to maintain a temperature of 41F). This slab will be open to atmosphere. There is an insulation layer of 2inches below the 300mmslab to retard heat from going subsurface. I will be using glycol tubing diameter 1in. The distance/space between glycol tubing coils/wraps will be 150mm.

With these given information, I need to calculate the BTU/hr heat load required to maintain the top of this slab at 41F as well as the length of glycol tubing that will be required.

Any idea supplied will be much appreciated.

Thanks,
