I don’t have your graphs or numeric data, so I can’t give the three accelerations yet. If you upload the speed–time graphs or give two points from the straight portion of each graph I will calculate them.
How to get each acceleration yourself:
- Pick two points on the linear (constant-acceleration) part of the speed–time curve for that fan speed: (t1, v1) and (t2, v2).
- Compute acceleration a = (v2 − v1) / (t2 − t1).
- Make sure v is in cm/s and t in s so a is in cm/s^2. (If v is in m/s, multiply by 100 to convert to cm/s before dividing.)
Example: if for Low fan v goes from 0 cm/s at t = 0 s to 40 cm/s at t = 5 s, then a = (40 − 0)/(5 − 0) = 8 cm/s^2.
Send the graph images or the (t,v) pairs for Low, Medium and High and I’ll compute the three accelerations.
