Chapter 10, Problem 10.148MP

Interpretation Introduction

(a)

Interpretation:

Temperature that corresponds to freezing point of water on Rankine scale is to be determined.

Concept introduction:

The formula to convert degree Rankine to kelvin is as follows:

$T_{\text{rankine}}=T\left(\text{K}\right)\cdot \frac{9}{5}$

Where

• $T_{\text{rankine}}$ denotes temperature in Rankine.
• $T\left(\text{K}\right)$ denotes temperature in kelvin.

Interpretation Introduction

(b)

Interpretation:

The value of gas constant in terms of Rankine scale is to be determined.

Concept introduction:

The relation between $\text{K}$ and

$\text{1 K}$ is equivalent to $\text{1}\text{.8 }°\text{R}$.

Interpretation Introduction

(c)

Interpretation:

The pressure of a gas at $\text{525 }°\text{R}$ is to be calculated from van der Waals equation.

Concept introduction:

The formula to convert degree Rankine to kelvin is as follows:

$T\left(\text{K}\right)=T_{\text{rankine}}\cdot \frac{5}{9}$

Van der Waals equation is given as follows:

$\left(P+\frac{a{n}^2}{V^2}\right)\left(V-nb\right)=nRT$
