16.050 TO THE RESCUE Entropy =loss(half of what I learned in 16.050 ? How do I measure entropy Who in the department has an entropy meter? What doi need to measure? Suppose my measurements have an"uncertainty of 1% of the dynamic pressure What would be a success? Suppose my measurements have an“ uncertainty”of±0.1%of the dynamic pressure What would be a success? Suppose my measurements have an"“ uncertainty”of±10%of the dynamic pressure Cani succeed? 1316.050 TO THE RESCUE • Entropy = loss (half of what I learned in 16.050) • How do I measure entropy? – Who in the department has an entropy meter? • What do I need to measure? • Suppose my measurements have an “uncertainty” of + 1% of the dynamic pressure – What would be a success? • Suppose my measurements have an “uncertainty” of + 0.1% of the dynamic pressure – What would be a success? • Suppose my measurements have an “uncertainty” of + 10% of the dynamic pressure – Can I succeed? 13
