Results of a standard compaction test (mold volume 943.9 cm3 ) are:

Trial No. 1 Mass of soil + mold 5619g
Mass of mold 3735g
Water content test
Mass of sample + container 288.26g
Mass of dry sample + container 265.39g
Mass of container 104.31g

Trial No. 2 Dry density 1795 kg/m^3 w=14.9%
Trial No. 3 Dry density 1828 kg/m^3 w=15.6%
Trial No. 4 Dry density 1832 kg/m^3 w=16.5%
Trial No. 5 Dry density 1796 kg/m^3 w=17.6%

a. Complete the calculations for trial No. 1.
b. Draw the moisture-density curve using Excel or other spreadsheet programs. Include ZAV curves at w=16%, 17%, and 18%. (The relative density of the soil is 2.65.) Find the maximum dry density and the optimum water content.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
