Expert Solution & Answer

Answer to Problem 13QP

The factor that affects the hardenability curve when having alloying elements other than carbon is explained below:

Explanation of Solution

The presence of other alloying elements (except carbon) in steel wills results less hardness.

The hardenability curve depicts the ability of the steel to be hardened. The hardenability curve is plotted with the results arrived from hardenability test. The hardenability test involves quenching as the final process, where the specimen is quenched in medium like water or oil. The process of quenching possesses the faster cooling rate that influences the hardness. The cooling rate is low at the distance from the quenched end. This low cooling rate enhances the diffusion of carbon and formation softer pearlite that may mingled with bainite and maternsite. Therefore, the hardenability of steel is increased. The other alloying elements do not encourage this activity. Thus, carbon is the only alloying element that gives more hardness and as well as hardenability whereas the other alloying element does not possess that much hardness and hardenability when compared to carbon.

A 2.5-m-long thin vertical plate is subjected to uniform heat flux on one side, while the other side is exposed to cool air at 5°C. The plate surface has an emissivity of 0.73, and its midpoint temperature is 55°C. Determine the heat flux subjected on the plate surface. Uniform heat flux -Plate, € = 0.73 Cool air 5°C 7 TSUIT Given: The properties of water at Tf,c= 30°C. k=0.02588 W/m.K, v=1.608 x 10-5 m²/s Pr = 0.7282 The heat flux subjected on the plate surface is W/m²

Hot water is flowing at an average velocity of 5.82 ft/s through a cast iron pipe (k=30 Btu/h-ft-°F) whose inner and outer diameters are 1.0 in and 1.2 in, respectively. The pipe passes through a 50-ft-long section of a basement whose temperature is 60°F. The emissivity of the outer surface of the pipe is 0.5, and the walls of the basement are also at about 60°F. If the inlet temperature of the water is 150°F and the heat transfer coefficient on the inner surface of the pipe is 30 Btu/h-ft².°F, determine the temperature drop of water as it passes through the basement. Evaluate air properties at a film temperature of 105°C and 1 atm pressure. The properties of air at 1 atm and the film temperature of (Ts+ T∞)/2 = (150+60)/2 = 105°F are k=0.01541 Btu/h-ft-°F. v=0.1838 × 10-3 ft2/s, Pr = 0.7253, and ẞ = 0.00177R-1
