Furthermore, it has lower heat loss and cost than those of a flat-plate collector-SWHS. Gunerhan and Hepbasli [148] studied the optimum tilt angle for solar collectors in Izmir, Turkey. It is found that the solar collector should be orientated due south and that it should be mounted ...
Although the problem is complicated by the differences in friction and lift coefficient, the scale effect is less predictable due to the quantity of both laminar flow in the boundary layer and the separation over the blade surfaces. Consequently, there is the potential for the extrapolation process...

“Water is the best of all things.” This saying of Pindar (518–446 B.C.) has not lost its meaning over the ages. A grain seed, properly stored for thousands of years in a pottery jar, has a good chance to germinate once exposed to the humid soil. A...
For example, at 70 gpm, 2" ID Sch 40 PVC pipe has a friction loss of 3.71 gpm. So I'll make a ballpark guess at your friction loss of say 5 gpm or roughly 20 lpm. That's 4% of the LPM flow rate that you want - probably not significant. So any pump sized to give 500 ...
A situation is eventually reached where the pump pressure equals the friction around the circuit, and the flowrate can increase no further. If the pump curve and the system characteristic curve are plotted on the same chart - Figure 6.3.5, the point at which the pump curve and...
Water contributes to weight loss by being an alternative to high-calorie beverages, which significantly contribute to obesity. A systematic review of the randomized clinical studies published in the Nutrición Hospitalaria journal in 2019 titled “Effect of water consumption on weight loss: a systematic...
Are you wondering if they are necessary? We think they are – here's why! Getting the Whole Picture When you evaluate or test nozzles, you can use formulas to calculate the flow rates and friction loss you are experiencing. However, these formulas are not foolproof. They are subject to ...
7.2.4 Bottom Friction Dissipation, Sbf The process of the dissipation of wave energy at the seabed may be modelled by the action of a stress (7.4)τ=−Cfρwub|ub| on water moving at a velocity ub just above the bottom boundary layer (Putnam and Johnson, 1949; Kajiura, 1968). The...
