Triesman and Geffen compared the attenuation theory with the late-selection theory. They asked subjects to indicate when they heard a target word, but the word could occur either in the shadowed or unattended ear. Their results suggest that:

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Air flows over a heated plate àt a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point.the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?
