Nitrogen, symbol N, is the chemical element of atomic number seven. At room temperature, it is a gas of diatomic molecules and is colorless and odorless.
Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied.
Flow measurement is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive-displacement flow meters accumulate a fixed volume of fluid and then count the num...
An electrolyte is a substance that ionizes when dissolved in suitable ionizing solvents such as water. This includes most soluble salts, acids, and bases. Some gases, such as hydrogen chloride, und...
