    Paschen curves obtained for helium, ... The graph of this equation is the Paschen curve. ... To keep the discharge going on, free electrons must be created at the ...

  3. Discharge coefficient - Wikipedia

    en.wikipedia.org/wiki/Discharge_coefficient

    In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, [1] i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures.

  4. Rating curve - Wikipedia

    en.wikipedia.org/wiki/Rating_curve

    In hydrology, a rating curve is a graph of discharge versus stage for a given point on a stream, usually at gauging stations, where the stream discharge is measured across the stream channel with a flow meter. [1] Numerous measurements of stream discharge are made over a range of stream stages.

  5. 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.

  6. Hydrograph - Wikipedia

    en.wikipedia.org/wiki/Hydrograph

    The discharge is measured at a specific point in a river and is typically time variant. Approach Segment the river flow before the storm (antecedent flow). Rising limb The rising limb of the hydrograph, also known as concentration curve, reflects a prolonged increase in discharge from a catchment area, typically in response to a rainfall event.

    en.wikipedia.org/wiki/File:Glow_discharge...

    English: Graph showing the characteristic (current vs. voltage) curve of a gas discharge in neon gas at a pressure of 1 torr, between two planar electrodes separated by 50 cm, showing the different discharge regimes.

  8. Streamflow - Wikipedia

    en.wikipedia.org/wiki/Streamflow

    However, in most cases the curve bends strongly, making it difficult to plot a projection accurately. This problem can be overcome by plotting the discharge and/or recurrence interval data on logarithmic graph paper. Once the plot is straightened, a line can be ruled drawn through the points.

  9. Peukert's law - Wikipedia

    en.wikipedia.org/wiki/Peukert's_law

    Peukert's law becomes a key issue in a battery electric vehicle, where batteries rated, for example, at a 20-hour discharge time are used at a much shorter discharge time of about 1 hour. At high load currents the internal resistance of a real battery dissipates significant power, reducing the power (watts) available to the load in addition to ...
