    en.wikipedia.org/wiki/Egyptian_units_of_measurement

    A number of units were used to measure mass. One oke was equal to 1.248 kg, according to the metric equivalences defined in 1891. [1] [2] Some other units according to the metric equivalences defined in 1891 are given below: [1] [2] 1 kirat = 1 ⁄ 6400 oke 1 dirhem = 1 ⁄ 400 oke 1 miskal = 8 ⁄ 800 oke 1 okieh = 0.03 oke 1 rotoli = 0.36 oke ...

    en.wikipedia.org/wiki/Aviation_fuel

    In performance calculations, airliner manufacturers use a density of jet fuel around 0.80 kg/L (6.7 lb/US gal; 8 lb/imp gal). Specific cases are: Bombardier Aerospace: The Challenger Multi-role Aircraft is a special mission variant of the Bombardier Challenger 650 business jet platform. Bombardier bases performance on the use of fuel with an ...

  4. Jet fuel - Wikipedia

    en.wikipedia.org/wiki/Jet_fuel

    Jet fuel is a mixture of a variety of hydrocarbons. Because the exact composition of jet fuel varies widely based on petroleum source, it is impossible to define jet fuel as a ratio of specific hydrocarbons. Jet fuel is therefore defined as a performance specification rather than a chemical compound. [1]

  5. Oka (mass) - Wikipedia

    en.wikipedia.org/wiki/Oka_(mass)

    In Egypt, the monetary oka weighted 1.23536 kg. In Tripolitania, it weighed 1.2208 kg, equal to 2½ artals. The oka was also used as a unit of volume. In Wallachia, it was 1.283 liters of liquid and 1.537 L of grain (dry measure). In Greece, an oka of oil was 1.280 kg, which would have translated to about 1.340 litres (at 0.916 kg/l).

    The main petroleum component used in blending avgas is alkylate, which is a mixture of various isooctanes. Some refineries also use reformate.All grades of avgas that meet CAN 2–3 [further explanation needed], 25-M82 [further explanation needed] have a density of 6.01 pounds per US gallon (720 g/L) at 15 °C (59 °F).

    The setat was the basic unit of land measure and may originally have varied in size across Egypt's nomes. [20] Later, it was equal to one square khet, where a khet measured 100 cubits. The setat could be divided into strips one khet long and ten cubit wide (a kha). [2] [6] [37] During the Old Kingdom:

  8. Flow measurement - Wikipedia

    en.wikipedia.org/wiki/Flow_measurement

    A multiple jet or multijet meter is a velocity type meter which has an impeller which rotates horizontally on a vertical shaft. The impeller element is in a housing in which multiple inlet ports direct the fluid flow at the impeller causing it to rotate in a specific direction in proportion to the flow velocity.

    The HA-300 fighter was originally designed around the 8,170 lbf (36.3 kN) afterburning Bristol Siddeley Orpheus Orpheus 703-S-10 turbojet, but aside from whether the British would even release it for use by the Egyptians, President Nasser saw that being dependent on a British engine was a major threat to national security, due to the potential ...
