Two flat, rectangular plates with a lateral dimension

Two flat, rectangular plates with a lateral dimension w*l lie parallel, one above the other, a distance h apart. The gap between them is filled with molten polymer. One plate is fixed; the other moves parallel to it in the direction of the dimension l at velocity v, causing the fluid to be sheared. Show that the fluid is displac ...continues

Hydrostatic relation

An empirical formula relating pressure and density for seawater w/ temperature held constant is: p/pa = (k+1)(q/qa)^7 - k where p= pressure pa = pressure at the surface k = dimensionless constant q = density qa = density at the surface Using the formula in the ...continues
