A building is to be constructed on a 50 ft deep, normally consolidated clay layer. The building applies a stress of 3000 psf on the ground surface. Compute the expected ultimate primary consolidation settlement of the clay layer. The clay has a saturated unit weight of 110 pcf. The compression index and recompression index of the clay layer are 0.2 and 0.04, respectively, with an initial void ratio of 0.9. Subdivide the clay layer into 5 layers.

Amass of 1.5 kg of air at 120 kpa and 24Β°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Water at 70Β°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.
