Acrew capsule has re-entered earth’s atmosphere and slowed to a speed of v=1134 m/s at an altitude where the static temperature is t=200 k and the static pressure is p=1 kpa. a normal shock forms upstream of the nose of the capsule. what is the pressure of the flow where it stagnates against the nose of the capsule? assume the air behaves as a calorically perfect gas with a ratio of specific heats γ=1.4 and gas constant r=287 j/kg/k.

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
