Air as an ideal gas with k51.4 enters a converging–diverging duct with a mach number of 2. at the inlet, the pressure is 26 lbf/in.2 and the temperature is 4458r. a normal shock stands at a location in the converging section of the duct, with mx5 1.5. at the exit of the duct, the pressure is 150 lbf/in.2 the flow is isentropic everywhere except in the immediate vicinity of the shock. determine temperature, in 8r, and the mach number at the exit

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

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
