Consider a laminar flow of water through a channel of a given round cross section which narrows from a first to a second segment by a factor of 3. The pressure in (the centre of) the second segment is measured through the filling level height in a vertical tube that is in fluid communication with the local flow field. The total pressure was 15 hPa and the flow velocity in the centre of the wider channel is 1.5 cm/s. What is the filling level in the vertical tube?

Consider a laminar flow of water through a channel of a given round cross section
which narrows from a first to a second segment by a factor of 3. The pressure in (the
centre of) the second segment is measured through the filling level height in a
vertical tube that is in fluid communication with the local flow field. The total pressure
was 15 hPa and the flow velocity in the centre of the wider channel is 1.5 cm/s.
