Equipment Inventory Numbers: Polythene Thickness Measurements (Micrometer Units): Rotary Vane Anemometer: Micrometer: Tape Measure: Average Polythene Thickness (Micrometer Units):

CALCULATIONS: Area of Circle = πr2

Volume Flow: Cross Sectional Estimated Volume Flow = Area of NPU Outlet X Mean Face Velocity (M 3/S) (M2) (M/S)

Estimation of Enclosure = Estimated Length X Estimated Width X Estimated Height Volume (M3) of Enclosure (M) of Enclosure (M) of Enclosure (M)

100M 3 Estimated Volume Estimated Volume Flow (M 3/S) X Estimation of Flow Per 100 M3 = Enclosure Volume 3 3 3 M /S / 100M (M )

Minimum Volume Flow = >0.1 M 3/S Per 100M3 (Area of a circle = r2)

Polythene Thickness:

Average thickness of polythene (m) = Micrometer units X 10 microns (m)

1000 gauge  250 microns (m)  25 micrometer divisions 500 gauge  125 microns (m)  12.5 micrometer divisions

Measurements recorded up to 10% below specified gauge can be accepted.
