    135135The tank was drained and cleaned in order to locate, drill and install the 2 Mhz UVPs at the apex of the first curve. The probes were located at 10 points evenly spaced 45 mm apart, starting 45 mm from the bottom.
    136136The results from the previous experiments were revised to plan new experiments and updated experimental plan and protocol were provided. A calibration for the conductivity probe on the traverse was plotted. Concentration profiles and plots were updated for the latest experiments. Post-processing of the UVP and ADP data for the conducted experiments were carried out. All of our data on the network was updated including the UVP and ADV.

    140140Experiment name: fixstr1_2609a,b.  Filenames: fixstr1_2609a, fixstr1_2609b. Location: Position 1 (75% down straight section, 58 cm upstream from the end of the straight section). Input rate 5.9 l/s. Density excess 19 kg/m3. Laser was not used in the experiments today. Running basal ADV with ADV !#1 located 7.2 cm, ADV !#2 located at 10 cm and ADV !#3 located at 12 cm above channel bed.

    153153Density of siphon samples from Monday, Sept 26 were measured. Two large PVC tubes (dia ~ 40 cm) were placed in the inlet box and weighted down to reduce the volume (new vol ~ 150 L).
     
    159159fixstr1_2709b: It was suggested to install an array of three conductivity probes in a cross-section just before the honeycomb in the inlet box. Only one additional probe was available. As such, two conductivity probes were mounted in the cross section just before the flow straightener (metallic honeycomb): one at the centerline (C2 green) and one 5 cm?? from the right wall (C1T1 black), looking downstream. The traverse was able to move vertically in every cross-section position and the previously outstanding issues have been resolved. Water was initially pumped with a flow rate of 15.28 l/s (55 m3/h). This was the highest achievable flow rate. The water was pumped at this rate for 2 minutes and then reduced to 6 l/s. This seems to achieve the desired effect of reaching a steady conductivity value in a short amount of time in the inlet box. The UVP was set over 10 minutes, but still showed noisy data. No siphon sampling was conducted.

Location: Position 1 (75% down straight section, 58 cm upstream from the end of the straight section). Input rate 20 l/s (initial ~ 2 minutes of each run) then reduced to 6 l/s. Density excess 18.4 kg/$m^3$. Laser was not used in the experiments today. Running basal ADV with ADV !#1 located 7.2 cm, ADV !#2 located at 10 cm and ADV !#3 located at 12 cm above channel bed.
