Avapor mixture of n-butane (b) and n-hexane (h) contains 50.0 mole% butane at 120 °c and 1 atm. a stream of this mixture flowing at a rate of 150.0 l/s is cooled and compressed, causing some but not all of the vapor to condense. (treat this process as a single-unit operation.) liquid and vapor product streams emerge from the process in equilibrium at t (°c) and 1100 mmhg. the vapor product contains 60.0 mole% butane. determine: a)the required final temperature (t) b)the composition of the liquid product (component mole fractions) c)the molar flow rates of the liquid and vapor products.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure

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
