Wind speed sensors typically involve a rotating element that is
set in motion by
wind. These sensor report the frequency of rotation of that
moving element. An
application receiving the frequency readings needs to apply a
"transfer function"
to translate the frequency to actual wind speed. In the weather
monitoring
station at Vancouver International Airport, two wind speed
sensors are installed:
an RM Young 05103 Wind Sensor and a Vaisala WM30 Wind Sensor.
The first
has the following transfer function: Wind Speed (m/s) = 0.0980 *
Frequency.
The second has this transfer function: Wind speed (m/s) = 0.699
*
Frequency – 0.24.
(a) If the RM Young sensor is reporting frequency of 20 Hz, and
assuming both
sensors are measuring the same wind speed value, then what would
be the
frequency reported by the Vasiala sensor?
(b) What would be the actual wind speed measured?
