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.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

What precautions should you take to prevent injuries when dealing with heavy loads?

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
