Karthigeyan . S

Mr.Vinay, yes empirical relationship between relative density and angle of internal friction is given in the text book titled Basic and Applied Soil Mechanics by Gopal Ranjan and A.S.R. Rao. You could able to see in the chapter named shallow foundation..

Vinay Bhushan Chauhan

Thank you Karthigeyan for the information.

Mr.Vinay you could able to find empirical relationship also in the same book as i mentioned earlier..
