A Newtonian Fluid flows steadily and continuously at 100oF through a 4500 foot horizontal pipe with constant cross-sectional area of 12.56 in2 . This fluid has a density of 53.6 lbm/ft3 , heat capacity of 0.420 BTU/lbm F and kinematic viscosity of 6.15x10-6 ft2 /sec. This pressure drop across the pipe under these conditions is 300 lbf/ft2 . Assuming fully developed, parabolic, laminar, incompressible flow, please calculate the maximum velocity and volumetric flow rate of the fluid in the pipe.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

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.
