FLUID MECHANICS - CASE STUDY

Introduction

Problem Graphic
A payload specialist at NASA needs to estimate the total weight of the experimental equipment that will be on board the space shuttle for an upcoming mission. Part of the experimental equipment includes fifteen compressed tanks filled with different gases (oxygen, nitrogen, and carbon dioxide).

Questions

The volume of the tank is 0.25 m3 and the mass of an empty tank is 5 kg. The conditions of the gases are summarized in the following table:

 Number ofTanks Temperature (K) Absolute Pressure (MPa) Oxygen 5 290 1.00 Nitrogen 4 290 0.85 Carbon Dioxide 6 290 1.25

Estimate the total weight of all of the compressed tanks.

Approach

• Assume the ideal gas law is applicable.
