Relationship between different types of speeds: cmp :cav :crms ::1:1.128:1.224cav = 0.9213crms crms = 1.086cav cmp = 0.816crms
explain how?(Cm.p) Most Probable speed :
C( rms)Root mean speed :
C(av) Average speed :
Note : K,T and m will cancel out in ration.
Ratio of Cav /Crms = (8/3π)1/2 = (2.6/3.14)1/2 = 0.921
Ratio of Crms /Cav = 1/0.921 = 1.08
Ratio of Cmp /Crms = (2/3)1/2= 0.816
Similarly Cmp : Cav : Crms = (2)1/2 : (8/π)1/2 : (3)1/2 = 0.82 : 0.92 : 1
