What minimum wattage must the heater have

Reference no: EM13560642

An electric heater is used to heat a room of volume 62m³ . Air is brought into the room at 5⁰ and its completely replaced twice perhour. Heat loss through the walls amounts to approximately 850kcal/h. If the air is to be maintained at 20^o C, what minimum wattage must the heater have? (The specific heat of air is about .17 kcal/kg.C^o . )
