Answer:
See explanation
Explanation:
Let the dye and gel be denoted by species A and B respectively.
Express the dimensionless concentration change with respect to the initial concentration of species A, when diffusion coefficient is constant.
…… (1)
Here, surface concentration of species A is , initial concentration of species A is , diffusion coefficient of species A in species B is , depth is z, error function is , time is t, and concentration of species A with respect to depth and time is .
Substitute 0 for and re-arrange Equation (1).
Answer:
D=1.0x10^-5 m^2/s
Explanation:
the data given by the exercise are as follows:
T=308 K
d=1 cm
PA=0.195 atm
pL=0.85 g/cm^3
The expression for binary gas-phase diffusion coefficient is equal to:
substituting the values in the diffusion equation:
from Appendix J-1 from Welty:
298 K, D=9.62x10^-5 m^2/s
At 308 K, we have the following:
Answer:
150 N
Explanation:
Moment is the product of force and distance:
27 N·m = F·(0.180 m)
F = 27 N·m/(0.180 m) = 150 N
The force required to produce the desired moment is 150 N.
