# How large should a static pressure be during a windtunnel test in the wake rake.? [closed]

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.

@DavidZaslavsky it can be removed. I was mixing up my numbers. – Aaron de Windt Mar 4 at 21:04
