Pressure drop in D0 Run2B stave

[摘要] The D0 Run2b stave structure has been tested to determine the pressure drop along the cooling line and suggest a possible cooling pipe size. The measured pressure drop, charted versus the flow rate, shows good agreement with what is theoretically predicted, the latter underestimating the experimental data in the worst case with a 5.5% error. At a fixed flow rate of 175-ml/min and bulk temperature of -15 C, a cooling pipe formed from a 0.158'' (4.0mm) ID tube would meet the 3.0 psi target pressure drop. With the same piping and a bulk temperature of -10 C the pressure drop is around 2.3 psi.
