Hi,
Is there any thumb rule for Placing Plumbing Pipe in slab?
what are measures and methods take in to account for Hunching desing?
Thanks for you time

Codes also specifiy a maximum level of shear stress to be respected; when the failure is expected to happen for a given thickness by compressive strut failure, then adding more shear (or tension) steel is of no use, and then the slab needs to be thickened at supports. Traditional rules for thickened regions in a diametral length talk of around 1/8 of the span; I have seen them (almost invariably in waffle slab) in almost anything between 1/10 and 1/3, yet the smaller should be the more economical, waffle or not.
Finally, and whilst you are not in regions where the principal compressive stresses at the concrete are near those limiting strut crushing, a limited run of some inclined inclusion 2" in diameters should not be structural concern; but still perpendicular insets are to be preferred given the easier maintenance of both the service and the structure itself, you will know in all cases where the pipe is.

For pipe penetration through floor, try to get away from high stress area. If couldn't avoid, add'l bars shall be added to transfer the stress.
