Calculate Convective Heat Transfer Coefficients Given data P

Calculate Convective Heat Transfer Coefficients:

Given data: Power was set to 20 Watts.

3 runs(shown below) ran at 1m/s, 2m/s, 3m/s. The bottom reading in each column represent the final temperature taken. All tempertures are in C.

Temp @ 1.0 M/s 96.3 93.1 91.1 89.9 88.7 88.1 87.4 87 Temp 2.0 M/s 86.7 84.6 82.2 80.4 79.2 78 77.1 Temp 3.0 M/s 76.9 74.3 72.5 71.1 69.9 69.1

Solution
