Description : Explain higher and lower calorific value of a coal having following composition by mass Carbon 81%,Hydrogen 7%, Oxygen 8%,Nitrogen 2.5%, sulphur 1.5% and remaining is ash
Last Answer : Carbon C = 81% = 0.81 Hydrogen = H2 = 7% = 0.07 Oxygen = O2 = 8% = 0.08 Nitrogen = N = 2.5% = 0.025 Sulphur = S =1.5% = 0.015 Ash = 2.5% = 0.025 Dulong's formula: H.C.V. of coal = 33800 C + 144500 ... = H.C.V.- 9H2 x 2442 KJ / Kg = 36187.5- 9 x 0.07 x 2442 L.C.V. of coal = 34649.04 KJ / Kg
Description : On selling a fan at 8% loss and an iron box at 18% gain, a man gains rs.346.If he sells the fan at 7% gain and the iron box at 15% gain, then he gains rs.450. The actual price of the iron box is approximately?
Last Answer : Let the cost price of the fan be Rs X and Cost of the iron box beRs Y Then 18%Y – 8% X=346 ; That is 18Y-8X=34600 1 And 15%Y+8% X=450 ; that is 15Y+8X=450002 Solving 1 and 2 we get X=1102.275 Y=2412.12 therefore cost of ironbox is = 2412(approx.)
