WebThe energy required to raise one cubic metre of air through one kelvin is 0.33 watt-hours, i.e. its heat capacity per cubic metre is 0.33 Wh m –3 K −1. Thus the total ventilation heat loss, Q v , will be: Q v = 0.33 × n × V × Δ T watts. For any given building, the actual ventilation rate will depend on its age and location. WebFor flue gas stacks and chimneys, where air is on the outside and combustion flue gases are on the inside, the equations will only provide an approximation and his the height of the flue gas...
WebIn the absence of stack effect, the formula does not apply. When applying the increase in pressure factor of 4.76 to our example, and given the original stack pressure of 0.38 at the first floor grille, the fan must now operate at a level to ensure 1.81 Ps in. w.g. at this same grille.
