Odd flow

Today I discovered two things. The first is a leak. This was fairly impressive: my prof and I stood at the whiteboard and discussed the symptoms, and diagnosed a leak as one likely thing that should be checked for.

The second thing I discovered is that when the valve says clack it does not necessarily mean that it is open. A bubble check told me that reality did not correspond to the computer screen. Suddenly the split inlet acts like a split inlet.
