What is the outside diameter of 5 inch pipe?

141.3 mm (5.563 in), in any schedule: it is the DN 125 pipe of ASME B36.10M. The wall changes with the schedule, and the inside diameter with it.

What is the wall thickness of 5 inch schedule 40 pipe?

6.55 mm (0.258 in), with an inside diameter of 128.20 mm (5.047 in); carbon steel pipe weighs 21.77 kg/m (14.63 lb/ft).

What is the difference between schedule 40 and 80 in 5 inch pipe?

The wall: 6.55 mm (0.258 in) in schedule 40 and 9.53 mm (0.375 in) in 80. The outside diameter is the same, so schedule 80 has the smaller bore -- 122.24 mm (4.813 in) against 128.20 mm (5.047 in) -- and weighs 30.97 kg/m (20.80 lb/ft) against 21.77 kg/m (14.63 lb/ft).

5 inch pipe (DN 125): outside diameter, wall thickness and weight by schedule

A 5 inch pipe (DN 125) has a 141.3 mm (5.563 in) outside diameter in every schedule: what changes is the wall, and with it the inside diameter and the weight. Designations that give the same wall share a row.

Schedule	Wall	ID	Weight
Sch 5 / 5S	2.77 mm (0.109 in)	135.76 mm (5.345 in)	9.46 kg/m (6.36 lb/ft)
Sch 10 / 10S	3.40 mm (0.134 in)	134.50 mm (5.295 in)	11.56 kg/m (7.78 lb/ft)
Sch 40 / STD / 40S	6.55 mm (0.258 in)	128.20 mm (5.047 in)	21.77 kg/m (14.63 lb/ft)
Sch 80 / XS / 80S	9.53 mm (0.375 in)	122.24 mm (4.813 in)	30.97 kg/m (20.80 lb/ft)
Sch 120	12.70 mm (0.500 in)	115.90 mm (4.563 in)	40.28 kg/m (27.06 lb/ft)
Sch 160	15.88 mm (0.625 in)	109.54 mm (4.313 in)	49.12 kg/m (32.99 lb/ft)
XXS	19.05 mm (0.750 in)	103.20 mm (4.063 in)	57.43 kg/m (38.59 lb/ft)

Plain-end weight of carbon steel pipe, by the standard's own formula: 10.69 × (D − t) × t in lb/ft, with D and t in inches (0.0246615 × (D − t) × t in kg/m, in mm). Austenitic stainless weighs about 2% more.
