Chapter 3, Problem 3.90P

(a)

Interpretation Introduction

Interpretation:

The feasibility of storing 35,000 kg of propane as a gas at $\text{10}\text{C}$ and 1 atm should be determined.

Concept Introduction:

The advantage of storing propane as a gas or as a liquid depends on the wall thickness of the tank which is given as:

  $\begin{array}{l}\text{t = }\frac{{\text{P}}_{\text{d}}\text{D}}{{\text{2fj+P}}_{\text{d}}}\\ \text{where:}\\ {\text{P}}_{\text{d}}\text{ = gas cylinder design pressure = Pressure of gas/liquid + constant}\\ \text{D = diameter of the cylinder}\\ \text{f = maximum allowable pressure}\\ \text{j = joint efficiency }\end{array}$

(b)

Interpretation Introduction

Interpretation:

The feasibility of storing 35,000 kg of propane as a liquid at $\text{10}\text{C}$ and 6.294 atm should be determined.
