Q1: Specific gravity of hot metal (pig iron) is __________ times that of the blast furnace slag.A 2
B 3
C 0.8
D 6
ANS:B - 3 The specific gravity of hot metal (pig iron) is generally higher than that of blast furnace slag. Typically, the specific gravity of pig iron is around 7.0 to 7.2, while the specific gravity of blast furnace slag is around 2.8 to 3.0. Given this information, we can calculate the ratio of the specific gravity of hot metal to blast furnace slag: Ratio=Specific gravity of pig iron/Specific gravity of blast furnace slag Ratio=7.0 (approximately)/2.8 to 3.0 Ratio≈2.33 to 2.5 So, the specific gravity of hot metal (pig iron) is approximately 2.33 to 2.5 times that of blast furnace slag. Among the given options, the closest match is: 3 |
