X-ray crystallography Wikipedia

X-ray crystallography (XRC) is the experimental science determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the

Flow Rate Calculator Good Calculators

What is Volumetric Flow Rate? The volumetric flow rate, which is also commonly referred to as the rate of liquid flow or volume flow rate, is the volume of a given fluid that flows within a unit of time.It is usually denoted by the Q symbol.. The rate at which a liquid flows will vary according to area of the pipe or channel through which it is passing and the velocity of the liquid.
