What is the friction factor for smooth dry pavement?
The friction factor used in the Darcy-Weisbach equation to calculate the pressure drop in pipe flows is dependent on the surface roughness inside the pipe and Reynolds number of the pipe flow. The relationship between the friction factor and the relative roughness, Reynolds number can be found in the Moody diagram.
What is the Volume in gallons of 6 inch pipe?
The pipe's volume is the product of its cross-sectional area and its length. The area of a circle is pi*(radius)^2, so in this case pi*9sq.in. or about 28.3 square inches. Multiply this area by the length of pipe you are using to obtain a volume. A 10 foot length of 6 inch pipe will have 3393 cubic inches of volume or 1.96 cubic feet, or 14.7 US Gallons.

Why are the solar panels usually painted black?
If they are PV panels or heat pipe panels, they are not painted at all, paint would stop them working. Only a simple hot water radiator panel would be painted black and you would do this because the colour black absorbs all solar radiation, other colours reflect some of the suns energy.
