However, most students in the middle level grades (6th, 7th and 8th) are unaware ofopportunities in engineering and do not recognize engineering as a rewarding career option.Furthermore, research tells us that women and minority students are drastically underrepresentedin the engineering fields.1 To more effectively prepare

Semiconductors’ (ITRS) prediction of a likely shift from synchronous to asynchronous design styles in order to increase circuit robustness, decrease power, and alleviate many clock-related issues 1. ITRS predicts that asynchronous circuits will account for 19% of chip area within the next 5 years, and 30% of chip area within the next 10 years 2. To meet this growing industry need, students in Computer Engineering should be introduced to asynchronous circuit design to make them more marketable and more prepared for the challenges faced by the digital design community for years to come. 1.

For the first two years of the program this course was offered everysemester and since then it has been offered only every fall semester. Enrollment in the coursehas now grown to the point where approximately 80 students sign up for the course every fall.The learning outcomes for EGR 110 are as follows: 1.

that operate bysensing all of the fluid in the pipe or channel. In the operation of a venturi meter, upstream anddownstream pressure taps are connected to a manometer or differential pressure transmitter (seeFigure 1). This pressure differential is then used to determine the flow rate by applying aBernoulli balance from the entry of the throat of the meter. The angle of the discharge cone istypically set between 5° and 15° to prevent boundary layer separation and to minimize friction.Typically, 90% of the pressure loss in the upstream cone is recovered, making the venturi veryuseful for measuring very large flow rates, where power losses can become economicallysignificant.
