Acapacitance sensor consists of two overlapping plates separated by a small gap filled with either a dielectric material or a vacuum. capacitance is changed by varying either the area of overlap, a, or changing the thickness of the gap,, such that calar of 600+ 0.3 mm2 and gap thickness of 0.30 0.01 mm, estimate the uncertainty in capacitance. let cs-8.85 x 10-15 f/mm, assume 95% confidence in all values and no an area correlated errors.

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.

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?
