Answer: b
Explanation: The permeability in air, small change in width and length is calculated first.
On substitution the specific permeance is calculated.
The formula for specific permeance (P) is given by:
[ P = frac{Q}{A cdot Delta P} ]
Where:
– ( P ) is the specific permeance (typically expressed in units of m²/Pa·s or similar).
– ( Q ) is the flow rate of the fluid (in cubic meters per second).
– ( A ) is the area through which the fluid is flowing (in square meters).
– ( Delta P ) is the pressure difference across the area (in Pascals).
