Flow rate calculation
The flow rate is calculated using the effective pressure method. This involves
comparing the static pressure upstream of the inlet nozzle with the static
pressure in the inlet nozzle.
The flow rate can be calculated from the effective pressure Δp
w
(differential pressure of the two static pressures) using the following equation.
The doors must be closed to determine the correct flow rate. Route the test
hoses through the unit floor to the outside when conducting the test.
