Peak Velocity Pressure (qb(z)): Section 4.5

Peak velocity pressure, qb, at height z is calculated according to the following equation:
qpz= 1+7 Ivz 12 ρ vm2z(4.8)
where
ρ
=
air density (1.25 kg/m3)

It is also possible to enter a constant value of qb in the program. In this case, there is no need to calculate vm and vb exclusively.
