Pace [6] in minutes per kilometre or mile vs. slope angle resulting from Naismith's rule [7] for basal speeds of 5 and 4 km / h. [n 1]The original Naismith's rule from 1892 says that one should allow one hour per three miles on the map and an additional hour per 2000 feet of ascent.
The values for most of the conversion factors used by Template:Convert come from international and national standards documents: . Organisation Intergouvernementale de la Convention du Mètre (2014) [2006].
Some extreme examples are NASCAR Sprint Cup Series and Formula one engines with ~25 m/s and Top Fuel and MotoGP engines ~30 m/s The mean of any function refers to the average value. In the case of mean piston speed, taken in a narrow mathematical sense, it is zero because half of the time the piston is moving up and half of the time the piston ...
These ratings are based on observed performance and any requisite adjustments generally become evident after 5-10 races have been sailed. Scoring options include Time-on-Distance or Time-on-Time. [1] While handicaps are assigned locally, US Sailing provides certain standards and guidelines to maintain a degree of consistency between fleets.
Each half of a flag depicts 5 knots (9.3 km/h; 5.8 mph) of wind. Each full flag depicts 10 knots (19 km/h; 12 mph) of wind. Each pennant (filled triangle) depicts 50 knots (93 km/h; 58 mph) of wind. [26] Winds are depicted as blowing from the direction the barb is facing.
During trials, on 9 February 1867 in Stokes Bay, Lord Clyde achieved 13.4 knots (24.8 km/h; 15.4 mph) from 6,064 indicated horsepower (4,522 kW) at an engine speed of 64.8 rpm and, on 13 September near Plymouth, Lord Warden achieved 13.5 knots (25.0 km/h; 15.5 mph) from 6,706 indicated horsepower (5,001 kW) at an engine speed of 62.3 rpm.

According to one source, [39] the wind gradient is not significant for sailboats when the wind is over 6 knots (because a wind speed of 10 knots at the surface corresponds to 15 knots at 300 meters, so the change in speed is negligible over the height of a sailboat's mast). According to the same source, the wind increases steadily with height ...
The 40 by 80 foot wind tunnel circuit was originally constructed in the 1940s and is now capable of providing test velocities up to 300 knots (560 km/h; 350 mph). [26] It is used to support an active research program in aerodynamics, dynamics, model noise, and full-scale aircraft and their components.
