Chapter 10, Problem 88E

Interpretation Introduction

Interpretation:

An enriched uranium is given to be produced by effusion of gaseous ${\text{UF}}_6$ across a porous membrane.
The ratio of effusion rate for ${}^{235}\text{U}$ and ${}^{238}\text{U}$ is to be calculated and the ratio for their effusion rates is to be compared with ${\text{UF}}_6$ .

Concept introduction: The ratio of effusion rate of gaseous molecule is calculated by the formula,
$\frac{r_1}{r_2}=\sqrt{\frac{{\text{μ}}_2}{{\text{μ}}_1}}$

To determine: The ratio of effusion rate for ${}^{235}\text{U}$ and ${}^{238}\text{U}$ and the ratio for their effusion rates with ${\text{UF}}_6$ .
