A high rise office building located in a city at sea level is exposed to a wind of 75 km/h. what is the static pressure of the airstream away from the influence of the building? what is the max pressure acting on the building? pressure measurements indicate that a value of Cp=-4 occurs near the corner of the wall parallel to the wind direction. If the internal pressure equals that of the free stream static pressure, what is the total force on the plane of glass 1m x 3m located in this regin?
