Describe electronegativity and explain the trend of electrnegativity in the periodic table

Inadequate stores control is not an obstacle to effective work order system. (clo4) 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.

The proportional limit is always greater than the yield strength for a material. a)-trune b)- false
