Question

1. A strong north wind (V- 60 mph) blows steadily toward the corner of a large "L'" shaped building (aerial view). The corner is at the junction of a long east facing wall, and a long north facing wall. The atmospheric pressure in the uniform stream approaching the building is equal to 14.47 psia, and the temperature is equal to 70 deg F. The streamline pattern in the vicinity of the corner (viewed from above) is close to that predicted by potential flow theory. At a location 4 ft. east of the corner and 3 ft north of the north facing wall, the velocity is equal to 5.0 ft/s. Calculate the pressure at the corner. Calculate the velocity at a location 2 ft east of the corner and 10 ft north of the north facing wall (Hints: A north wind originates from the north. The corner is clearly the inside corner of the “L", and the east facing wall would be illuminated by sunlight on a clear morning.)
