2. Hybrid (golf) - Wikipedia

   en.wikipedia.org/wiki/Hybrid_(golf)

   A hybrid is a type of club used in the sport of golf with a design borrowing from both irons and woods while differing from both. The name "hybrid" comes from genetics to denote a mixture of two different species with desirable characteristics of both, and the term here has been generalized, combining the familiar swing mechanics of an iron with the more forgiving nature and better distance of ...

3. Shaft (golf) - Wikipedia

   en.wikipedia.org/wiki/Shaft_(golf)

   The shaft is roughly .58 inch/14.7 millimeters in diameter near the grip and between 35 and 48 inches/89–115 cm in length. Shafts weigh between 45 and 150 grams depending on the material and length. Graphite shafts are woven from carbon fiber and are generally lighter in weight than steel shafts. Graphite shafts became popular among amateurs ...

4. Brake-specific fuel consumption - Wikipedia

6. Watt-hour per kilogram - Wikipedia

   en.wikipedia.org/wiki/Watt-hour_per_kilogram

   The batteries that Tesla uses in their electric cars deliver about 254 W⋅h/kg, [1] compared to supercapacitors that are typically rated between 3 and 10 W⋅h/kg, [2] with the best commercially available supercapacitors as high as 47 W⋅h/kg. [3] Nuclear batteries based on betavoltaics can reach up to 3300 W⋅h/kg, although over much longer ...

   en.wikipedia.org/wiki/Hybrid_vehicle_drivetrain

   NRG Dynamix of the U.S.A. claimed its approach reduced cost by one-third compared with electric hybrids and added only 300 lbs (136 kg) to vehicle weight vs. 1,000 lbs (454 kg) for electric hybrids. The company claimed a standard pickup vehicle powered by a 2.3-litre, 4-cylinder engine achieved 14 mpg (16.8 L/100 km) in city driving.

9. Useful conversions and formulas for air dispersion modeling

   Meteorological data includes wind speeds which may be expressed as statute miles per hour, knots, or meters per second. Here are the conversion factors for those various expressions of wind speed: 1 m/s = 2.237 statute mile/h = 1.944 knots 1 knot = 1.151 statute mile/h = 0.514 m/s 1 statute mile/h = 0.869 knots = 0.447 m/s.
