We did some experiments for an assignment and I'm getting some confusing results here. When I try to calculate the pressure coefficient it is about $-60$. When I looked at the measured static pressure it is in average around $1500 \text{ Pa}$. Meanwhile the barometric pressure is about, $1025 \text{ hPa}$ and the dynamic pressure $1560 \text{ Pa}$.

I have no idea what I'm doing wrong.

Hi user21614, and welcome to Physics Stack Exchange! This is a site for conceptual questions about physics, not general homework help. If you can edit your question to ask about the specific physics concept that is giving you trouble, I'll be happy to reopen it. See our FAQ and homework policy for more information. – David Zaslavsky♦ Mar 4 at 20:25
@DavidZaslavsky it can be removed. I was mixing up my numbers. – Aaron de Windt Mar 4 at 21:04
