A Study on Some Simple Apparatus to DemotlBtrate Hydraulic Principles
간단한 교시용 수리실험장치에 관한 연구
Abstract
Some simple devices to demonstrate important hydraulic principles to students are necessitated in fluid mechanics or hydraulics classes. These devices should\ulcorner be easy to make and operate with inexpensive cost. The writer has studied some simple demonstrhation apparatus of hydraulic principles which were made with cheap materials. The purpose of this paper is to present the results of the study. In this paper, hydraulic principles that can be demonstrated by using these apparatus are described, the plans of them are presented, and how to make them and what materiaIs to be used are briefly explained. An axial-flow fan is a device with which the flow of air is supplied for several purposes. It consists of a duct, a fan and a guide vane. It may be possible to demonstrate the principles of propeIler,drag force, lift, etc.
