Draw a fourbar linkage with L1 = 10 cm, L2 = 3 cm L3 = 6 cm and L4 = 6 cm, with LaTeX: \theta_2θ 2= 45o. Consider both configurations in your drawing, namely the open and closed. Measure your transmission angles and indicate which is which. Do you see a difference in values?

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.
