2. Installed capacity for electricity production in India as on 31.03.17 was
- Around 145 GW
- Around 226 GW
- Around 326 GW
- Around 500 GW
3. Global CO2 (Atmospheric CO2) level reported in June, 2017 was:
- Around 109 ppm
- Around 209 ppm
- Around 309 ppm
- Around 409 ppm
4. Match the following emissions from the fossil fuels through conventional routes in best possible combination
- 1(a,e), 2(b,f), 3(c,g), 4(d,h)
- 1(a,f), 2(b,e), 3(c,g), 4(d,h)
- 1(a,e), 2(b,f), 3(c,h), 4(d,g)
- None of these
5. HHV of the Bituminous coal is:
- HHV: 5000-15000 KJ/Kg
- HHV: 15000-25000 KJ/Kg
- HHV: 25000-35000 KJ/Kg
- HHV: 35000-45000 KJ/Kg
6. Which moisture type is an integral part of the coal seam in its natural state, including water in pores but excluding that in macroscopically visible fractures?
- Inherent moisture
- Equilibrium moisture
- Total moisture
- Residual moisture
7. What is true about swelling index of coal
- It helps to test the coking property of coal.
- Swelling index varying between 2 to 5 is ideal for coke manufacturing
- The high swelling coal is not charged for coke making as it would create unnecessary pressure on the side wall of the oven will also produce a coke porous structure
- All of these
8. Which one is true about energy equivalent of the calorimeter

- W=(Hg∗M+E1+E2)/ΔT
- W=(Hg∗M+E2+E3)/ΔT
- None of these
9. Which one is not a classification of thermodynamics cycles?
- Topping cycle
- Bottoming cycle
- Combine cycle
- None of these
