Force 300-19R wind loading
Ensure that the device and the structure on which it is mounted are capable of withstanding the
prevalent wind speeds at a proposed ePMP site. Wind speed statistics are available from national
meteorological offices.
The device and its mounting bracket are capable of withstanding wind speeds of up to 180 kph (113 mph).
Wind blowing on the device will subject the mounting structure to significant lateral force. The
magnitude of the force depends on both wind strength and the surface area of the device. Wind loading
is estimated using the following formulae:
Force (in kilograms) = 0.1045aV
2
Where:
Is:
a
the surface area in square meters
V
wind speed in meters per second
Force (in pounds) = 0.0042Av
2
Where:
Is:
A
the surface area in square feet
v
wind speed in miles per hour
Applying these formulae to the ePMP device at different wind speeds, the resulting wind loadings are
shown in Table 58-and Table 59.
