PEX tubing

Does anybody know the heat loss per foot for 3/4" PEX running through a 0F slab with 140F entering water temp?

    heat loss in PEX

    Here comes the dreaded answer.....it depends !!!! Flow rate, temperature of the slab, downward heat loss, temperature of the space....they all contribute to the heat transfer rate....do the calculations to know what the BTU/sq ft will be.
