v233 v234 387 387 '''Friday, October 14th 2016''' 388 388 389 Density of the previous siphon samples were measured and recorded. Two experiments were conducted in which the tank was rotated with a rate of 0.0104 rad/s (0.1 rpm) in the clockwise direction, which corresponds to a Rossby number of -8.390 . 389 Density of the previous siphon samples were measured and recorded. Also 3 guests were at Coriolis to visit the site and see the experiments. Two experiments were conducted in which the tank was rotated with a rate of 0.0104 rad/s (0.1 rpm) in the clockwise direction, which corresponds to a Rossby number of -8. 390 391 391 Experiment name: rotstr1_1410a, rotapex2_1410b. File names: rotstr1_1410a, rotapex2_1410b. 392 392 393 rotstr1_1410a: 394 395 396 rotapex2_1410b: 397 393 rotstr1_1410a: The total experiment time was 36 mins. Inflow rate started with 10.36 L/s and then was decreased to 5.75 L/s until it reached a constant level. PIV measurements were also conducted. Density excess and temperature were 20.5 kg/m^3^ and 22.3°C, respectively. ADV data were collected at the straight section (Position X1 - 75% down straight section, 56 cm upstream from the end of the straight section) from 15 to 25 min after the flow rate became constant. 7 sets of siphon samples were collected at 5, 10, 15, 20, 25, 30, and 35 minutes after the start of the experiment, with duration of 1 minute. The cross stream UVP collected data from 5 to 15 minutes, and the down-stream UVP collected data from 25 to 35 minutes. 394 395 rotapex2_1410b:The total experiment was 30 minutes. Temperature and density excess were 22.4°C and 20.1 kg/m^3^, respectively. Inflow rate started with 10.58 L/s and then was decreased to 5.83 L/s until it reached a constant level. ADV measurements were collected from 15 to 35 minutes after the start of the experiment at the second apex (Position X4). 398 396 399 397 '''Monday, October 17th 2016''' 400 398 401 399 Density of the previous siphon samples were measured and recorded. One experiment was conducted in which the tank was rotated with a rate of 0.0052 rad/s (0.05 rpm) in the clockwise direction, which corresponds to a Rossby number of -16. 402 . 400 403 401 Experiment name: rotstr1_1710a. File names: rotstr1_1710a. 404 402 405 403 rotstr1_1710a: The total experiment time was 36 mins. Inflow rate started with 10.61 L/s and then was decreased to 5.83 L/s until it reached a constant level. PIV measurements were conducted. Density excess and temperature were 20.1 kg/m^3^ and 22.3°C, respectively. ADV data were collected at the straight section (Position X1 - 75% down straight section, 56 cm upstream from the end of the straight section) from 15 to 25 min after the flow rate became constant. 7 sets of siphon samples were collected at 5, 10, 15, 20, 25, 30, and 35 minutes after the start of the experiment, with duration of 1 minute. The cross stream UVP collected data from 5 to 15 minutes, and the down-stream UVP collected data from 25 to 35 minutes. 406 404 407 When measuring the density of the siphon samples for this experiment it was revealed that the ambient was too salty so no experiments commenced and the tank was drained. 408 409 410 The tank was drained, washed and cleaned. Then it was filled and rotated with 0.041 rad/s (0.4 rpm) corresponding to Rossby number of +2. Wiki notes were prepared and the website was updated. All files on the LEGI network were also updated. 411 405 When measuring the density of the siphon samples for this experiment it was revealed that the ambient was too salty in the current experiment and the one conducted on Friday. Therefore, no experiments commenced and the tank was drained immediately. Furthermore, Wiki notes were prepared and the website was updated. All files on the LEGI network were also updated. 412 406 413 407 '''Tuesday, October 18th 2016''' 414 408 409 The tank was washed and cleaned. Then it was filled and one experiment was conducted where the tank was fixed which corresponds to a Rossby number of infinity. 410 415 411 '''Wednesday, October 19th 2016''' 416 412
