# Pressure distributions around solid objects

1. The problem statement, all variables and given/known data

What is the $$p_\infty$$ term that arises in many expressions for pressure distributions around solid objects?

2. Relevant equations

An example is $$p = p_\infty - \frac{7}{2}\cos \theta$$

3. The attempt at a solution

I've seen the $$p_\infty$$ come up very often in expressions for pressure fields so I'm guessing that it's some kind of convention to put it in. Does it refer to the pressure very far away or is it the pressure at a stagnation point?
