Since the wind load factor of 1.3 included this effect, it must be Search: Generator Load Calculation Formula. There is a common misconception that the calculated occupant load is the maximum number of occupants the space can contain.
Most of the time, uplift load is countered by the weight of the roofs dead load, but in areas prone to strong storms and greater wind speeds mean that the uplift load is increased, too, and that has to be included in any load calculations. R 1 = 1270 lbs. Add the stove, and I'm looking at two out of three phases having a draw of 129.4A give or take. Now each square meter of the slab would have a self-weight of 0.125 x 1 x 2400 = 300 kg which is equivalent to 3 kN. Lets Take the values of P (Watt) and Voltage Determine the size of the room.
