Answer :
The law that relates the absolute pressure to atmospheric pressure and gauge pressure is Pascal law.
What is Pascal law?
Pascal's law states that when an object is immersed in a fluid, it experiences equal pressure on all surfaces.
P = Patm + pgh
where;
- P is absolute pressure
- pgh is gauge pressure
- Patm is atmospheric pressure
Thus, the law that relates the absolute pressure to atmospheric pressure and gauge pressure is Pascal law.
