For those of you who take sandcastle building very seriously, listen up: MIT engineers now say you can trust a very simple equation to calculate the force required to push a shovel -- and any other ...

Tests for a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a non-Newtonian fluid. Sept. 15, 2003 Click on the pdf link below to view ...

Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...

Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and ...
