      <subfield code="a">Equations are derived to model installed exhaust ventilation systems using measured diameters, flows, and pressures. The system of equations does not require knowledge of system components or their loss coefficients except for those components that will be replaced. The modeling procedure is demonstrated for an example problem in which observed values are created for initial and final conditions from velocity pressure loss coefficients</subfield>
