You would like to measure wind speed with a cup anemometer on a sailboat trip across the Atlantic Ocean. The measure of the rotational speed of the axle of the device has a precision of +/-0.2 rotations/s and was calibrated in a steady wind-tunnel flow at 20m/s with 10 rotations/s. Define for the below-given situations, 1 to 4, the type of error (random or systematic) and explain how to overcome or reduce this error.

Question
![(a)
You would like to measure wind speed with a cup anemometer on a sailboat trip
across the Atlantic Ocean. The measure of the rotational speed of the axle of the
device has a precision of +/-0.2 rotations/s and was calibrated in a steady wind-tunnel
flow at 20m/s with 10 rotations/s. Define for the below-given situations, 1 to 4, the
type of error (random or systematic) and explain how to overcome or reduce this
error.
1
Bearing of the axle is old
2
Turbulent flow
3
Icing on the cups
4
Strong tumbling of the sailboat
You would like to use it for a measure of the in-cabin air flow a quiet environment.
Discuss why the measurement system is not well posed for this purpose.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7989d58a-7af6-4c73-a4d8-3a66f200f066%2F948b0762-814f-49c8-b4e7-0b6020fa206c%2Flail789_processed.jpeg&w=3840&q=75)
