In a frenzied first-half passage of play Mat Ryan made two desperate saves from Ashley Barnes and Jack Cork, with the ball breaking for Long, who hit a post.
According to the shown spectra, the main frequencies in the volute are the impeller rotation frequency and its harmonic (25 and 100 Hz), the half blade passage frequency (74 Hz), the blade passage frequency and its harmonics (148 and 296 Hz), and the broadband frequency [15].
The dominant pressure fluctuation frequencies are composed of impeller rotation frequency and its harmonic frequencies, and half blade passage frequency.
The amplitudes of pressure fluctuations on half blade passage frequency at 0.2 and 1.2 Qn are 3.9 and 1.6 times of that at the best efficiency point, respectively.
The pressure fluctuation characteristics are affected largely by impeller rotation, whose dominant frequencies include impeller rotation frequency and its harmonic frequencies, and half blade passage frequency.
The pressure fluctuations on half blade passage frequency in Figure 9 show that the amplitude of the pressure fluctuation on such frequency at l.2 Qn is two times as large as that at 1.0 Qn.
For the pressure fluctuations on point S3, the amplitudes at half blade passage frequency and four times impeller rotation frequency are much larger than that on points S1 and S2.
The pressure fluctuations in the suction chamber are considerably affected by the rotation effect, of which the frequencies are manifested as the harmonic of impeller rotation frequency and half blade passage frequency.
In marked contrast, 75% of the GEPT-A reading items on the form analyzed had moderate, broad, or very broad scope, requiring test takers to extract the necessary information from most or all of a paragraph, more than one paragraph, or more than half the passage, respectively.
Consider this half-page passage about clouds bunching over the ocean: "I knew, watching them, that if in any given moment a measurement could be made it would show how tentative was my mind's mastery over my heart.
Eventually, permission to continue was given and the research ship Polarstern made a two-and-half-month passage through stormy seas following the bloom that the researchers had created.In this section The beast that will not die Who ate all the algae?
