1. An apparatus for flow rate testing of a testing fluid through a tube having an inlet end and an outlet end, the apparatus comprising:

  • a hydraulic power unit providing an inlet pressure to move the testing fluid through the tube, the hydraulic power unit having an inlet and an outlet;

    a plurality of test equipment connected in series with the tube, comprising;

    a flow meter measuring a flow rate of the testing fluid through the tube;

    a pressure gauge measuring the inlet pressure; and

    an accelerometer measuring sound and vibration of the tube, wherein a first of the plurality of test equipment is connected to the outlet of the hydraulic power unit and a last of the plurality of test equipment is connected to the inlet end of the tube;

    a reservoir tank supplying the testing fluid to the hydraulic power unit and collecting the testing fluid from the tube, the reservoir tank having an inlet connected to the outlet end of the tube and an outlet connected to inlet of the hydraulic power unit; and
