It is found empirically [Jho, C., and Carreras, M., J. Colloid Interface Sci., 99, 543 (1984)] that in systems which have a time-dependent surface tensions s (t) (such as dilute surfactant solutions), the appropriate drop mass M(t) to be used in the formulae for calculation of s by the drop weight method is given by .

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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

Agas mixture consists of 8 kmol of h2 and 2 kmol of n2. determine the mass of each gas and the apparent gas constant of the mixture.
