The pressure rise p associated with wind hitting a window of a building can be
estimated using the formula p = rho(v2
/2), where rho is density of air and v is the speed of the
wind. apply the grid method to calculate pressure rise for rho = 1.2 kg/m3
and v = 100 km/h.

a. express your answer in pascals.
b. express your answer in meters of water column (m-h2o).

a)P=462.70 Pa

b)h = 0.047 m of water

Explanation:

Given that

Pressure ,

V= 100 km/h

V=27.77 m/s

The pressure P

P=462.70 Pa

We know that density of the water

Lets height of the water column = h m

We know that

462.70 = 1000 x 9.81 h

h = 0.047 m of water

a)P=462.70 Pa

b)h = 0.047 m of water
