Alarge artery in a person’s body can be approximated by a tube of diameter 9 mm and length 0.35 m. also assume that blood has a viscosity of approximately 4 ×10-3 n-s/m2 , a specific gravity of 1.0, and the pressure at the beginning of the artery is equivalent to 146 mm hg. if the flow were steady with v = 0.2 m/s, determine the pressure at the end of the artery if it is oriented(a) vertically up (flow up) (b) horizontal.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

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?
