Is relative roughness dimensionless?

Is relative roughness dimensionless? Since the relative roughness is a dimensionless number, both the absolute roughness and diameter must carry the same units. What is equivalent roughness? The equivalent roughness of a mine roadway can be defined. as the roughness of a circular pipe, of which diameter is. equal to the hydraulic diameter of the […]

What is the gain of non-inverting amplifier?

What is the gain of non-inverting amplifier? A non-inverting amplifier uses a voltage-divider-bias negative feedback connection. The voltage gain is always greater than one. The voltage gain is positive, indicating that for AC input, the output is in-phase with the input signal and for dc input the output polarity is same as the input polarity. […]
