The object below is to be cast from aluminum (a cube with a hollow conical volume). If you have problems reading the drawing, the cube side is 100 mm, the cone height is 60 mm and the cone base radius is 30mm. Aluminum data: Density = 2.7 g/cm3, Melting Temperature = 660 °C, Cs = Cl = 0.4 J/g.°C, Hf = 200 J/g, Determine:- The volume of the part to be cast (3 points),- The area of the part to be cast (3 points),- Required energy to heat the metal (3 points),- Solidification time function of the mold constant Cm

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
