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
one of
e an

The experiments with static charges were done by:

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
