Answer:
a. 430.944 pascal
b. 0.0625psi
c. 1.73008inH20
Explanation:
The pressure rise Ap associated with wind hitting a win- dow of a building can be estimated using the formula Ap-p(12/2), where p is density of air and V is the speed of the wind. Apply the grid method to calculate pressure rise for P-1.2 kg/m and V-60 mph. a. Express your answer in pascals. b. Express your answer in pounds-force per square inch (psi). c. Express your answer in inches of water column
checking the dimensional consistency
Dp=
convert 1 mile to meter
1mile=1609m
1h=3600s
60mile/h=26.8m/s
slotting intpo the relation
430.944kg/(ms^2)
which is the same as 430.944N/m^2
expressing in pascal.
We know that
1 pascal=1 N/m^2
430.944 pascal
2. 1 pascal=0.000145psi
answer=0.0625psi
3.1 pascal=0.00401inH20
answer=430.944*0.0040146
1.73008inH20
