1) A room heater burns liquid fuel and the following data are available: 

Density of liquid fuel = 8.0 × 102kg/m^3 
Energy produced by 1 m^3 of liquid fuel = 2.7 × 1010 J 
Rate at which fuel is consumed = 0.13 g/s 
Temperature at which air enters heater = 12 °C 
Temperature at which air leaves heater = 32 °C 
Specific heat capacity of air = 990 J/kg*K 

a) Use the data to calculate the power output of the room heater, ignoring the power required to convert the liquid fuel into a gas.
