HM 240.04 Cylinder Pressure Distribution
Education / GUNT Hamburg / Fluid Mechanics and Hydrology / Steady Incompressible Flow /


 The HM 240.04, designed as an accessory for the HM 240 Computer Linked Air Flow Bench, comprises a hollow metal cylinder with pressure measurement hole and a potentiometer for angle measurement. For the experiments the cylinder is inserted in a mounting in the HM 240 Bench. For the pressure measurements there is a connection on the cylinder via which the pressure measuring hole is connected to the pressure sensor in the HM 240.
