If a vacuum line much smaller than the flange diameter of the turbopump (DN 100 (100 mm)) is used, the effective pumping speed will decrease. A DN 25 (25 mm) vacuum line will result in only around 7.4 ...
The total energy of the ball consists of its potential energy (related to position) plus its kinetic energy (related to motion). To zero out both components, you would have to give a precise value to ...
Researchers developed aluminum structures that trap air bubbles, making them able to float perpetually in even the harshest environments.
