Explanation:
using the energy equation for entry and exit value :
where
L.H.S = R.H.S
Answer:
Explanation:
Diffusion flux of a gas, J is given by
where
is permeability coefficient,
P is pressure difference and x is thickness of membrane.
The pressure difference will be 10,000 Pa- 3000 Pa= 7000 Pa
At 298 K, the permeability coefficient of water vapour through polypropylene sheet is
Since the thickness of sheet is given as 1mm= 0.1 cm then
Therefore, the diffusion flux is
