3. Soil has been compacted in an embankment at a bulk mass density rho of 2.15 Mg/m^3 and water content w of 12%. Gs is 2.65. Calculate dry mass density, void ratio, degree of saturation and air content. Would it be possible to compact this soil at w = 13.5% to a dry mass density rhod of 2.00 Mg/m^3?

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false
