Calculation of air exchange in multi-storey buildings using electronic computers.

Describes a computer program used to calculate the air exchange in multi- storey buildings. An air network is drawn up for the building and arbitrary initial pressures are assigned. A system of equations is drawn up for all linearly independent loops andjunctions and the program solves this system of equations. States that comparison with the hydraulic analogy method gives a discrepancy, not greater than about 3%. NOTES translation available from B.S.R.I.A. price 1 pound
