Assume A generator (15KVA) as an energy open system that consuming fuel with air and with generator producing electricity.
fuel specification:
Q= 100 lit/hr
Hv= 39500 Kj/kg
density= 780 kg/ m3
Other data:
A/F= 21
1 m3 air= 1.2 kg
fuel inlet diameter= 1 in
air inlet diameter= 85 mm
Outlet:
velocity= 1.25 cm/sec
density= 6.3 kg/m3
diameter= 25 cm
temperature= 350 C
Hv(heat value)= 2150 kj/Kg
Calculate:
1. energy surface changes
2. energy Volume Changes at 8 hours
3. differential changes in surface & volume system
