A) 15 points calculate the glide plane for the following dislocations: b = 1/2[-110], = [-110] b = 1/2[-1-12], = [1-10] b = 1/2[1-21], = [-18-7] b = 1/2[-101], = [101] b = 1/2[112], = [213] b) 10 points what is the character of each dislocation? which dislocations are perfect, which ones are partial? are there any that would not glide and why?

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
