Solution
Energy = 700 x 10³ Cal.
1 cal = 4.18 joules
2.92 x 10⁶ Joules = 7 x 10⁵ Cal.
Power = Energy / time
= 2.92 x 10⁶ / 3600
= 0.081 x 10⁴
= 8.1 x 10²
= 810 watts /hr
= 0.81 KW / h
1 cal = 4.18 joules
2.92 x 10⁶ Joules = 7 x 10⁵ Cal.
Power = Energy / time
= 2.92 x 10⁶ / 3600
= 0.081 x 10⁴
= 8.1 x 10²
