Wind blows on the side of a fully enclosed hospital located on open flat terrain where V= 120 mi/h. Determine the external pressure acting on the leeward wall, if the length and width of the building are 200 ft and the height is 30 ft. Take Ke 1.0.

The external pressure is p = -21.9 psf or p = -8.85 psf

Explanation:

Given :

Velocity of wind, v = 120 mi / hr

  (wind direction factor)

 = topographical factor (for flat terrain)

= velocity pressure at height h

But for height h = 30 ft, = 0.98 (from table)

        = 36.16

Now, ,   so (from table)

where, p = external pressure

            G = 0.85 = gust factor (for typical rigid building)

              (internal pressure co efficient)

Therefore putting the values,

p = -21.9 psf or p = -8.85 psf

the correct answer is c.stops after infancy and childhood.

myelin is the substance of the central nervous system (cns) that insulates nerve cell axons to increase the speed at which nerve impulse travels. myelination is a process of myelin formation. this process occurs postnatally, begins in the embryo during the midst of early development and finishes after birth.
