In an AC circuit having both resistive and reactive components, the power consumed can be calculated using the following formula: Power Triangle Active power, P = VI.CosΦ Reactive Power, Q = VI.SinΦ Complex Power S = VI.CosΦ + j.VI.SinΦ Apparent power, |S| = VI = I2Z Where ...
Active Power: Active power is the useful power consumed in a circuit, measured in watts (W), and does real work. Reactive Power: Reactive power supports the voltage levels necessary for active power transfer but does no useful work itself, measured in volt-amperes reactive (VAR). Complex Pow...
According to the formula: D = 0.3 × Ps [m3/h] D = 0.3 × (200 × 7) = 420 [m3/h] Where: D– Minimal efficiency of ventilators Ps– Total power loss od acceptor circuit Taking into account the rules above, following cubicle was selected: ...
