Laboratory experiments and computer models for studying the mass transfer process of removing CO2 from air using water or dilute NaOH solution as absorbent are presented. Models tie experiment to theory and give a visual representation of concentration profiles and also illustrate the two-film theory and the relative importance of various…

This paper addresses a controversy regarding the effect of bottle material on the thermal performance of beverage bottles. Experiments and calculations that verify or refute advertising claims and represent an interesting way to teach heat transfer fundamentals are described. Heat transfer coefficients and the resistance to heat transfer offered…

Presents the third part of a series on the development and implementation of project-based spiral curriculum in chemical engineering. Focuses on the details of the assessment design, describes the results of the assessment, and draws conclusions about the success of the program. (Contains 18 references.) (ASK)

Reports the development, delivery, and assessment of a project-based spiral curriculum for the first sequence chemical engineering courses. Technical proficiency of students under the spiral curriculum was equal to or better than that of students under a traditional curriculum. Attitudes toward chemical engineering and teamwork were better, and…
