Pressure loss coefficients for single phase flow through 90 degree bend has been estimated using CFD simulation. It is evident from the results that a validated CFD model is a reliable and cheap tool for loss coefficient estimation of any combination of pipe fitting and complex fluid / flow. ...
(32.14)Δ(gH)=Kp(K1V22+K2V22)(bend 1 loss)+(bend 2 loss) Figures 32.34–32.36 give information on Kp values for the configurations shown in Figure 32.37. Sign in to download full-size image Figure 32.34. Interaction coefficient: combination bends (after Miller6) Sign in to dow...
This move is simple, but effective. Stand with your feet hip-width apart. Bend at the knees and extend your arms behind you. Jump forward a few feet, swinging your arms up toward the sky for momentum. Land softly with knees bent. Using the same movements, jump backward a few feet. Bo...
We conducted a randomized controlled trial to examine the effect of two energy-restricted diets on body weight (BW), visceral fat (VF) loss, and the risk factors for metabolic syndrome. A total of 144 centrally obese postmenopausal women were assigned to
A ring-based optical isolator on silicon with bonded MO garnets is realized for the first time, as shown inFigure 11.20Cerium-substituted YIG (Ce:YIG) is chosen as the MO material, because of its high Faraday coefficient and low optical loss (10–15 dB cm−1) in the 1550-nm regime....
The larger the coefficient of variation, the higher the degree of dispersion. This section uses the data on each stable section of the shield and does not take into account the long-term shutdown section. The ground loss rate rises with an increase in the coefficient of variation on the ...

Spearman coefficient was used to make correlations. A p-value < 0.05 was considered statistically significant. All analyses were completed using the Statistical Package for Social Science (IBM Corp. Released 2013. IBM SPSS Statistics for Windows, Version 26.0. Armonk, NY, USA: IBM Corp.). ...
The kinetic energy recovery coefficient is the key indicator to evaluate the hydraulic performance of outlet conduit. The higher the kinetic energy recovery coefficient is, the greater the recovery degree of outlet cross-section water kinetic energy is. The kinetic energy recovery coefficient of outlet...
