Concept Introduction:
On the temperature-composition graph of an alloy, the curve above which the alloy exist in the liquid phase is the liquidus curve. The temperature at this curve is maximum known as liquidus temperature at which the crystals in the alloy can coexist with its melt in the
Solidus curve is the locus of the temperature on the temperature composition graph of an alloy, beyond which the alloy is completely in solid phase. The temperature at this curve is minimum known as solidus temperature at which the crystals in the alloy can coexist with its melt in the thermodynamic equilibrium.
Freezing range for an alloy is the difference of the liquidus and the solidus temperature of an alloy. In this range, the alloy melt starts to crystallize at liquidus temperature and solidifies when reaches solidus temperature.

Nitrogen is now compressed slowly in a polytropic process during which PV1.3 = constant until the volume is reduced by one-half. Determine the work done and the heat transfer for this process. The gas constant of N2 is R = 0.2968 kPa·m3/kg·K. The cv value of N2 at the anticipated average temperature of 350 K is 0.744 kJ/kg·K (Table A-2b). The work done for this process is kJ.

An average hole drift velocity of 103 cm/sec results when 2V is applied across a 1 cm long semiconductor bar. What is the hole mobility inside the bar? b. Name the two dominant carrier scattering mechanisms in nondegeneratedly doped semiconductors of device quality. c. For a give semiconductor the carrier mobilities in intrinsic material are (choose one: higher than, lower than, the same as) those in heavily doped material. Briefly explain why the mobilites in intrinsic material are (chosen answer) those in heavily doped material.arrow_forwardDuring a picnic on a hot summer day, all the cold drinks disappear quickly, and the only available drinks are those at the ambient temperature of 85°F. In an effort to cool a 12- fluid-oz drink in a can, a person grabs the can and starts shaking it in the iced water of the chest at 32°F. Using the properties of water for the drink, determine the mass of ice that will melt by the time the canned drink cools to 37°F. The density and specific heat of water at the average temperature of (85+37)/2 = 61ºF are ρ = 62.3 lbm/ft3 and cp = 1.0 Btu/lbmºF (Table A-3E). The heat of fusion of water is 143.5 Btu/lbm. The mass of ice that will melt by the time the canned drink cools to 37°F is lbm.arrow_forward
- Steam enters a nozzle at 400°C and 800 kPa with a velocity of 10 m/s and leaves at 375°C and 400 kPa while losing heat at a rate of 26.5 kW. For an inlet area of 800 cm2, determine the velocity and the volume flow rate of the steam at the nozzle exit. Use steam tables. At the left side of the lines, 800 kilo Pascal, 400 degree Centigrade, 10 meters per second are shown. At the right side of the lines, 400 kilo Pascal, 375 degree Centigrade are shown. The velocity of the steam at the nozzle exit is m/s.
