The normally used equation for calculation of infiltration flow rates into a house is a power law of which the exponent n is normally assumed to be 0.66 but sometimes values of 0.5 or even 1 can be seen in the literature. In this paper the constant n is calculated assuming a non fully developed infiltration flow. The constant n will for this assumption take values between 0.67 and 0.77 if the slots where the flow takes place are long enough to get a flow close to a developed one.
