Attach a test equipment with the test circuit shown in Fig. (3). Next, pour water at 5 to 40C, then measure the flow rate with a
pressure difference of 0.075 MPa. However, the pressure difference needs to be set with a large enough difference so that the
Reynolds number does not go below a range of 4 x 10
By substituting the measurement results for formula (8) to figure out
