This project is intended to generate a set of demo 1) loss within the format consists of 3 tubes. The loss within the pipe bend 90 degrees and 45 degrees.. reducing pipe size 2) to add a teaching demonstration series working principle Interior pipe loss rate, 3, 3) format, the quality of the demo series, finding the flow in pipes, 3, and 4) to format the contents of the performance demonstration Kit pipe flow rate in 3 formats.Dayaphu expert, which is expert training series comprised the side structure is equal to the total average 4.51 is in good appearance criteria to use. The total average results equal to 4.5 on a scale of good and the suitability to work. The total average results equal to 4.05 in good appearance and maintenance. The total average 4.8 on a scale equal to, which is consistent with a set of demo specialists rate the loss within the pipe 3 format has put to the test with a sample of undergraduate students third year mechanical engineering faculty of education industry. Rajamangala University of technology suvarnabhumi 2558 academic year number of 20 people to find performance test scores before and after each test study is thought and 85.2 65.8 percent, respectively. Therefore, according to the results of the lesson performance criteria that define 80/80 for the achievement of the students, which analyzed to compare with the average score is a statistical distribution formula (t-test) values calculated t value is higher than the crisis at 19.91 significance level 0.05 (1.699) which showed that the participants have a thorough knowledge from using air conditioning Demo Kit.
