  2. Fourth power law - Wikipedia

    en.wikipedia.org/wiki/Fourth_power_law

    This example illustrates how a car and a truck affect the surface of a road differently according to the fourth power law. Car (total weight 2 tonnes, 2 axles): load per axle: 1 tonnes; Truck (total weight 30 tonnes, 3 axles): load per axle: 10 tonnes = =, times as large

  3. Loss given default - Wikipedia

    en.wikipedia.org/wiki/Loss_given_default

    The LGD calculation is easily understood with the help of an example: If the client defaults with an outstanding debt of $200,000 and the bank or insurance is able to sell the security (e.g. a condo) for a net price of $160,000 (including costs related to the repurchase), then the LGD is 20% (= $40,000 / $200,000).

  4. Per-unit system - Wikipedia

    en.wikipedia.org/wiki/Per-unit_system

    As an example of how per-unit is used, consider a three-phase power transmission system that deals with powers of the order of 500 MW and uses a nominal voltage of 138 kV for transmission. We arbitrarily select S b a s e = 500 M V A {\\displaystyle S_{\\mathrm {base} }=500\\,\\mathrm {MVA} } , and use the nominal voltage 138 kV as the base ...

  5. Energy return on investment - Wikipedia

    The issue is still subject of numerous studies, and prompting academic argument. That's mainly because the "energy invested" critically depends on technology, methodology, and system boundary assumptions, resulting in a range from a maximum of 2000 kWh/m 2 of module area down to a minimum of 300 kWh/m 2 with a median value of 585 kWh/m 2 according to a meta-study from 2013.

  7. Passenger car equivalent - Wikipedia

    en.wikipedia.org/wiki/Passenger_car_equivalent

    Passenger car equivalent (PCE) or passenger car unit (PCU) is a metric used in transportation engineering to assess traffic-flow rate on a highway. [1]A passenger car equivalent is essentially the impact that a mode of transport has on traffic variables (such as headway, speed, density) compared to a single car.

  9. Mass balance - Wikipedia

    en.wikipedia.org/wiki/Mass_balance

    In environmental monitoring, the term budget calculations is used to describe mass balance equations where they are used to evaluate the monitoring data (comparing input and output, etc.). In biology , the dynamic energy budget theory for metabolic organisation makes explicit use of mass and energy balance.
