WebUtilizing the new wind speed maps necessitates the introduction of the terms V ult and V asd to be associated with “ultimate” design wind speed and the “nominal” design wind speed respectively. ASCE 7-10 defines the term V as the basic wind speed corresponding to a 3-sec gust speed at 33 ft. above the ground in Exposure Category C. WebMore information from the unit converter. How many pascal in 1 psf? The answer is 47.880258888889. We assume you are converting between pascal and pound/square foot.You can view more details on each measurement unit: pascal or psf The SI derived unit for pressure is the pascal. 1 pascal is equal to 0.020885434273039 psf.
