Curvature of earth per km
WebWorking backward with our 30° and 20° angles of sunbeams, and knowing Earth’s circumference to be about 40,000 km, the trees would have to be some 1,100 km apart (40,000 km/36). In practice, one would want to work with trees closer together. At 110 km apart, the arc distance between them would subtend a 1° angle at Earth’s center. WebIn practice, to find , one must be using a value of 8.5·10 3 km for the effective Earth's radius (4/3 of it), instead of the real one. So the equation becomes: = And for the same examples : the radar horizon for the radar at a 1-mile (1.6 km) altitude will be 102-mile (164 km) and the one at 75 feet (23 m) will be 12-mile (19 km). ...

WebUsing the theorem of Pythagoras a 2 = 3963 2 + 1 2 = 15705370 and thus a = 3963.000126 miles. Thus your position is 3963.000126 - 3963 = 0.000126 miles above the surface of the earth. 0.000126 miles = 12*5280*0.000126 = 7.98 inches.
