This report describes work done at the Cambridge University Department of Chemical Engineeering during the first year of an IFPRI contract. Most of the year’s work was spent on two aspects of the project, a literature survey and the development of a computer program to predict the rate of deaeration of a powder in a baker. The report on the former has been completed and is attached with this report. The results of the computer analysis have been written up in the form of a “final report” which it is hoped to distribute to IFPRI members by the end of next month.

In the present report we confine ourselves to details of the other aspects of the work during the year. This report therefore consists of the following sections:

1. Introduction

2. Experimental measurement of stress-strain curves.

3. A report of some small flowrate measurements to investigate the effects of interstitial pressure gradient on flowrate.

4. Future work.

5. The current technical and fiscal status of the project.
