Carbon black begins as a byproduct of what is referred to as partial oxidation, a process during which crude oil residues, such as vacuum residues from crude oil distillation or residues from the thermic cracking process, split due to the effects of the mixture of oxygen and water steam under high temperatures around 1,300 °C.
Air turbine used in a dental handpiece Correlation between rotational speed and torque Correlation between rotational speed and turbine output power. The turbine is powered by compressed air between 35 and 61 pounds per square inch (~2,4 to 4,2 bar), [1] [2] which passes up the centre of the instrument and rotates a Pelton wheel in the head of the handpiece.
