The solute hcl is diffusing through a thin film of water 2 mm thick at 283k. The conc. Of hcl at point 1 is 12wt%hcl (density is 1060kg/m3) and at point 2 is 6 wt%( density= 1030). The diffusivity is 2.45*10^-9 m2/sec. Calculate flux of hcl. ​

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
