Fanning friction factor — The Fanning friction factor is a dimensionless number used in fluid flow calculations. It is related to the Shear stress at the wall as:: au = frac{ f ho v^2}{2}where:* au is the shear stress at the wall *f is the Fanning friction factor of the… … Wikipedia
Hydraulic head — is a specific measurement of water pressure or total energy per unit weight above a geodetic datum. It is usually measured as a water surface elevation, expressed in units of length, but represents the energy at the entrance (or bottom) of a… … Wikipedia
Total dynamic head — (TDH) is the total height that a fluid is to be pumped, taking into account friction losses in the pipe.TDH = Static Lift + Static Height + Friction Losswhere: Static Lift is the height the water will rise before arriving at the pump (also known… … Wikipedia
Cylinder head porting — refers to the process of modifying the intake and exhaust ports of an internal combustion engine to improve the quality and quantity of the air flow. Cylinder heads, as manufactured, are usually suboptimal due to design and manufacturing… … Wikipedia
Darcy–Weisbach equation — In fluid dynamics, the Darcy–Weisbach equation is a phenomenological equation, which relates the head loss or pressure loss due to friction along a given length of pipe to the average velocity of the fluid flow. The equation is named after Henry… … Wikipedia
Darcy-Weisbach equation — The Darcy Weisbach equation is an important and widely used phenomenological equation in hydraulics. It relates the head loss or pressure loss due to friction along a given length of pipe to the average velocity of the fluid flow. Head loss form… … Wikipedia
