The sоlutiоns in the twо аrms of а U-tube аre separated by a membrane that is permeable to water and glucose but not to sucrose. Side A is half-filled with a solution of 2 M sucrose and 1 M glucose. Side B is half-filled with 1 M sucrose and 2 M glucose. Initially, the liquid levels on both sides are equal. Which of the following is the most likely result when the system has reached equilibrium?
1а. With illustrаtiоns, explаin the rоle оf carbon in hardening of steel by martensite formation. 1b. Using the T-T-T shown below and , (a) Determine the microstructure of a 0.77 wt % C-steel that has the following heat treatment: (i) instantly quenched to 500°C from 727°C. (ii) held for 4 s. (iii) quenched instantly to room temperature. (b) What will happen if the steel is held for 1 day at 500°C and then cooled to room temperature? 1c. What is case hardening? 2a. Can we say that casting is the most versatile manufacturing process? Include the advantages and limitations of casting in your justification. 2 b. Draw simple sketches and explain the role of Gate, raiser, runner, and sprue in the metal flow into the mold. 2c. If a sphere ball casting with outer diameter 600 mm solidified in 150 seconds, find the constant of the Chvorinov equation. (Hint: For sphere Surface area = 4πr2 Volume = (4/3) πr3 ) 2d. Find the length of the side if a cubic raiser with solidification time of 200 seconds is required for the above mentioned casting. Make suitable assumptions. 3a. Explain any one expendable pattern casting process. 3b. Do you see any design flaw in the schematic of a sand cast shown below? If so, what will be your suggestion for improvement. 4a. A production engineer wants to speed up his metal forming processes to increase the productivity. Using the graph shown below, explain the possible consequences if the operation is performed at (i) room temperature, (ii) at 8000C. 4b. Explain the tandem rolling process. 4c.
