  2. Torricelli's law - Wikipedia

    en.wikipedia.org/wiki/Torricelli's_law

    In many cases, such experiments do not confirm the presented discharge theory: when comparing the theoretical predictions of the discharge process with measurements, very large differences can be found in such cases. In reality, the tank usually drains much more slowly. Looking at the discharge formula

  3. Discharge (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Discharge_(hydrology)

    A discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass. Thus the water discharge of a tap (faucet) can be measured with a measuring jug and a stopwatch. Here the discharge might be 1 litre per 15 seconds, equivalent to 67 ml/second or 4 litres/minute. This is an average measure.

  4. Volumetric flow rate - Wikipedia

    en.wikipedia.org/wiki/Volumetric_flow_rate

    In hydrometry, the volumetric flow rate is known as discharge. Volumetric flow rate should not be confused with volumetric flux, as defined by Darcy's law and represented by the symbol q, with units of m 3 /(m 2 ·s), that is, m·s −1. The integration of a flux over an area gives the volumetric flow rate. The SI unit is cubic metres per ...

  5. Darcy's law - Wikipedia

    en.wikipedia.org/wiki/Darcy's_law

    Darcy's law is an equation that describes the flow of a fluid through a porous medium and through a Hele-Shaw cell.The law was formulated by Henry Darcy based on results of experiments [1] on the flow of water through beds of sand, forming the basis of hydrogeology, a branch of earth sciences.

  6. Paschen's law - Wikipedia

    en.wikipedia.org/wiki/Paschen's_law

    Paschen's law is an equation that gives the breakdown voltage, that is, the voltage necessary to start a discharge or electric arc, between two electrodes in a gas as a function of pressure and gap length. [2] [3] It is named after Friedrich Paschen who discovered it empirically in 1889. [4]

  7. Karl Fischer titration - Wikipedia

    en.wikipedia.org/wiki/Karl_Fischer_titration

    In analytical chemistry, Karl Fischer titration is a classic titration method that uses coulometric or volumetric titration to determine trace amounts of water in a sample. It was invented in 1935 by the German chemist Karl Fischer. [1] [2] Today, the titration is done with an automated Karl Fischer titrator.

  8. Manning formula - Wikipedia

    en.wikipedia.org/wiki/Manning_formula

    The Manning formula or Manning's equation is an empirical formula ... of a channel that controls water discharge. It also determines how much work the channel can do ...

  9. Miller–Urey experiment - Wikipedia

    en.wikipedia.org/wiki/Miller–Urey_experiment

    The experiment used methane (CH 4), ammonia (NH 3), hydrogen (H 2), in ratio 2:2:1, and water (H 2 O). Applying an electric arc (simulating lightning) resulted in the production of amino acids. It is regarded as a groundbreaking experiment, and the classic experiment investigating the origin of life (abiogenesis).
