4. Proposed Solution For air:(  vA) 1 = (  vA) 2 Assume  = 0 Therefore: (vA) 1 = (vA) 2 From geometry: A =  (htan   Therefore v 1 h 1 2 = v 2 h 2 2 v 1 /v 2 = (h 2 /h 1 ) 2 Based on our values of v, we find h 2 /h 1 = 1.011 Compressed Air h1h1 h2h2 A2A2 A1A1

5. Proposed Solution “Good” lentils = 772 kg/m^3 “Bad” lentils = 709 kg/m^3 From K. Carman: V t = 10.79 +.04M c B d =1212 - 8.94M c Equating and solving for B d yields: V t, good = 12.76 m/s V t, bad = 13.04 m/s This does not make sense! Compressed Air Good Lentils Chaff ∆h ∆s Bad Lentils
