Calculate the compression ratio of an engine with a stroke of 1.5 inches, a bore of 3.8 inches and a clearance volume of 1.25 cubic inches. discuss whether or not this a realistic compression ratio for a street engine and what type of fuel it would need to run correctly. would this engine be considered under-square or over-square?

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
