Units not compatible solve block

Can anyone look at this and tell me what I'm doing wrong?

The error message says it - your units don't balance. This applies to the first, second and fifth equation.

Check your equations and the units they contain.

In those equations the left hand side gives pressure, but the right hand side pressure per area!

Thanks. I missed that!
