Every time you sprint through the halls because you're late for class, score against your opponents during a game, or shoot pool with friends, you're using your bones, muscles, and joints. Without these important body parts, you'd be seriously sidelined â you'd be unable to sit, stand, walk, or do any of the activities you do every day.
2. Determine the total wattage needed for the room. Older homes with less insulation will use about 10 watts to heat each square foot. Newer homes with greater insulation values will only use about 6 watts per square feet. It will take approximately 600 watts to heat a 100 square foot room in a newer home.Older homes will need as much as 1,000 watts for the same room.. Calculate how large the baseboard heater will be. Baseboard heaters use about 250 watts of power for every foot of length. In a 100-square foot room that is part of an older home, the baseboard heater will be approximately 5 feet long. In a newer home, it will be about 3 feet long.
How much energy does it take to raise the temperature of an average room by 10 degrees? Assume the room is about 300 square feet and is in a well insulated building.Assume the temperature of the room is to be raised from 60 degrees F to 70 degrees F, or whatever makes the calculations easy.Assume the ceiling height is average, and that there are minimal losses (maybe some heat escapes via windows or under the doorway).ssuming the height of the room is about 10 ft tall, the total volume of the room is 10 x 300 = 3000 cu.ft. Amount of energy needed to raise temperature is given by the formula: specific heat capacity of substance x mass of substance x temperature difference.
