Hygrometer. Dry / Wet-bulb temperature. v. t. e. Psychrometrics (or psychrometry, from Greek ψυχρόν (psuchron) 'cold', and μέτρον (metron) 'means of measurement'; [1] [2] also called hygrometry) is the field of engineering concerned with the physical and thermodynamic properties of gas - vapor mixtures .
Pure physics is a branch of fundamental science (also called basic science). Physics is also called " the fundamental science" because all branches of natural science like chemistry, astronomy, geology, and biology are constrained by laws of physics. [60] Similarly, chemistry is often called the central science because of its role in linking ...
Nuclear physics. In nuclear physics, the semi-empirical mass formula ( SEMF) (sometimes also called the Weizsäcker formula, Bethe–Weizsäcker formula, or Bethe–Weizsäcker mass formula to distinguish it from the Bethe–Weizsäcker process) is used to approximate the mass of an atomic nucleus from its number of protons and neutrons.
Smith chart. The Smith chart (sometimes also called Smith diagram, Mizuhashi chart ( 水橋チャート ), Mizuhashi–Smith chart ( 水橋スミスチャート ), [1] [2] [3] Volpert–Smith chart ( Диаграмма Вольперта—Смита) [4] [5] or Mizuhashi–Volpert–Smith chart ), is a graphical calculator or nomogram designed ...
Deflection (physics) An object hitting a surface is an example of deflection. In physics, deflection is a change in a moving object's velocity, hence its trajectory, as a consequence of contact ( collision) with a surface or the influence of a non-contact force field. Examples of the former include a ball bouncing off the ground or a bat ...
Moody chart. In engineering, the Moody chart or Moody diagram (also Stanton diagram) is a graph in non-dimensional form that relates the Darcy–Weisbach friction factor fD, Reynolds number Re, and surface roughness for fully developed flow in a circular pipe. It can be used to predict pressure drop or flow rate down such a pipe.
The physics becomes closely similar although the nuclear density is about 15 orders of magnitude larger than that of ordinary matter and the nature of the dipole interaction is totally different. The correction was predicted in 1963 by Magda Ericson [3] and was derived in 1966 together with Torleif Ericson . [4]
EWMA chart. In statistical quality control, the EWMA chart (or exponentially weighted moving average chart) is a type of control chart used to monitor either variables or attributes-type data using the monitored business or industrial process 's entire history of output. [1] While other control charts treat rational subgroups of samples ...
