The space between two very long parallel plates separated by a distance h is filled with a fluid with viscosity
where μ0 is a constant and n is a constant exponent. The top plate slides to the right with a constant speed V0, as shown
a. Find the velocity distribution between the plates, and an expression for the shear stress τ.
b. Graph the shear stress versus the shear strain rate V0/h for several values of n > 0 (dilatant), n = 0 (Newtonian), and n
Oil is being driven upwards along the inclined plane by a belt moving with a constant velocity of U= 1 m/s. The width of the belt is b=1 m and its length is L = 20 m. Calculate the mass flow rate of oil
a long power transmission cable is buried at a depth ground-to-cable-centerline distance of 2 m. the cable is encased
A spherical vessel used as a reactor for producing pharmaceuticals has a 5 - mm - thick stainless steel wall (k = 17 W/m middot K) and an inner diameter of D, = 1.0 m. During production, the vessel is filled with reactants for which p = 1100 kg/m3 an..
Ten cubic feet of air is cooled at a constant pressure of 80 psi. The initial temperature is 180 0F and the final temperature is 100 0F. Assume air is an ideal gas, Cp = 0.241 Btu/lb 0R and Cv = 0.173 Btu/lb 0R and R = 1545 lbf/lbmol 0R, M = 28.97 lb..
