In October 2001, Environment Canada introduced the wind chill index above. Each curve represents the combination of air temperature and wind speed that would produce the given wind chill value. For example, a temperature of -25°C and wind speed...
The formula for wind chill C (in ees Fahrenheit) is given by C-35.74 0.6215T- 35.75v0.16 + 0.42750.16 where v is the wind speed in miles per hour and T is the temperature in degrees Fahrenheit. The wind speed is 27 ± 3 miles per hour and the temperature is 8 1. Use dC to estimate the maximum possible propagated error (round your answer to four decimal places) and relative error in calculating the wind chill (round your answer to two...
3. The wave heights h in the open sea depend on the speed v of the wind and the length of time t that the wind has been blowing at that speed. Values of the function h(v, t) have been experimentally determined and the results are recorded in feet in the following table. Here wind speed v is measured in knots and the duration t is measured in hours h(t, v)t 5 t-10 t 15 t 20 t 30 t-40...

The wind-chill index w is the perceived temperature when the actual temperature is T C) and the windspeed is u (km/h), so we can write W-f(T ) . Consider the followi table and respond to the following items: a. Estimate the values of fr - 15, 30) andf(-15, 30). What are the practical interpretations of these values? b.

Ex.3 /35 A Cessna 172 has a cruise speed V-226 km/h and weight W-1,000Kg. The wing area is S-16mt with a wing span b-1lm Assuming the wing rectangular, what is the Reynolds number at an altitude z-1,000m. A model of this airplane, scaled by a factor of 2, is tested in a wind tunnel at sea level. What should be the velocity in the wind tunnel to have dynamics similarity (neglect Mach number effects). What will be the lift measured...
