Measuring air density, attenuation of cone pendulum, each air indicator

摘要

This design is an idea IP designed to solve the problem of air density. The present invention is a hydrodynamic and classical mechanics subdivision of science and technology. To solve the air density measurement and each air indicator measurement task by the damping of the conical pendulum for convenience of everyday life 1. Convenience 2. Practicality 3. Verification in terms of sustainability. Unlike the existing invention, the pendulum and the air resistance are measured to make it easy for the user to use in keeping with the modern society.;
