[Dsg-eic_tracker] EIC beam line test stand flow test

[Amrit Yegneswaran]

marc,
make the plot from 1200 onwards i.e. for flow 150 -250 lpm
it appears that at these  flow rates the temperature of RTD C is around  27 C

Hi Patrizia and Rolf,

The flow tests are complete. The beam line pipe was heated to ~100C and air was flowed at 10, 20, 50, 100, 150, 200, and 250 liters per minute. Each flow test ran for 3 hours. After each test the controls waited for 3 hours to allow monitored temperatures to recover to approximately the same starting temperature for every test.

Sensor locations:

RTD_A, B, and C - inner surface of outer pipe (silicon)

RTD_D - outer surface of inner pipe (beryllium beam pipe)

RTD_H1, and H2 - outer surface of the heated pipe (for controls)

Brian,

The full data log is located at O:\DSG\EIC\Software\LabVIEW\Teststand_data\0502_0504_flowtest.xlsx<file:///O:\DSG\EIC\Software\LabVIEW\Teststand_data\0502_0504_flowtest.xlsx>


Regards,
Marc
