Question

O rezolvare, cu explicații va rog... ​

Answer 1

Q = ΔHcomb.x1000/22,4 (pt. combustibili gazosi)

=> ΔHcomb. = 22,4Q/1000

1 Nm3 CH4 ................................ 35816 kJ

180 Nm3 CH4 ........................... Q = 6446880 kJ

=> ΔHcomb. = 22,4x6446880/1000 = 144410 kJ

1 Nm3 C4H10 ...........................  11861 kJ

=> ΔHcomb. = 22,4Q(C4H10)/1000

= 22,4x118616/1000 = 26568 kJ

1 Nm3 ...................................... 2657 kJ

v Nm3 ....................................... 144410 kJ

= 54,35 m3 C4H10

Q = ΔHcomb.x1000/miu (pt. combustibili lichizi si solizi)

1 kg motorina ........................... 43100 kJ

a kg ............................................. 6446880 kJ

= 149,6 kg motorina
