14. in 1805, rear-admiral beaufort created
a numerical scale to sailors quickly
assess the strength of the wind. the
integer scale ranges from 0 to 12. the wind
scale, b, is related to the wind velocity, v,
in kilometres per hour, by the formula
b = 1.33vv + 10.0 – 3.49, v 2 -10.
a) determine the wind scale for a wind
velocity of 40 km/h. v
