What is the full meaning of LPU?
Acronym. Definition. LPU. Lyceum of the Philippines University.
How do you make an ultra high vacuum?
UHV conditions are created by pumping the gas out of a UHV chamber. At these low pressures the mean free path of a gas molecule is greater than approximately 40 km, so the gas is in free molecular flow, and gas molecules will collide with the chamber walls many times before colliding with each other.
What does LPU mean sneakers?
LPU – Latest Pick Up. Showing off the latest shoe that a sneakerhead picked up.
Is LPU under CHED?
LPU is an IQuAME Category A Teaching University and was deputized for Expanded Tertiary Education Equivalency and Accreditation Program (ETEEAP) by CHED. In addition, all LPU’s programs are accredited by PACUCOA and certified by Federation of Accrediting Agencies of the Philippines (FAAP).
How does a turbo pump work?
These pumps work on the principle that gas molecules can be given momentum in a desired direction by repeated collision with a moving solid surface. In a turbomolecular pump, a rapidly spinning fan rotor ‘hits’ gas molecules from the inlet of the pump towards the exhaust in order to create or maintain a vacuum.
What pressure is vacuum?
Vacuum can refer to any pressure between 0 PSIA and 14.7 PSIA and consequently must be further defined. For applications concerned with measuring vacuum pressures over this full range, two different approaches are often taken. Vacuum pressure is measured relative to ambient atmospheric pressure.
What is low vacuum?
Low vacuum is often measured in millimeters of mercury (mmHg) or pascals (Pa) below standard atmospheric pressure. “Below atmospheric” means that the absolute pressure is equal to the current atmospheric pressure. In other words, most low vacuum gauges that read, for example 50.79 Torr.
What does SC mean in shoes?
Usage: SC is the GOAT sneaker magazine. Special Edition. Abbreviated, that’s SE. At this point, it really doesn’t mean anything.
What are PE shoes?
Player exclusive shoes are special versions of a sneaker given to professional athletes.
What does BG mean in shoes?
ago. Additional comment actions. BG – Boys Grade School GG – Girls Grade School GS – Grade School. 3.
How many LPU are there in Philippines?
six campuses
Currently, there are six campuses in LPU. These are Manila (1952), Batangas (1966), Laguna (2000), Makati (2003), Cavite (2008) and the newest campus will open this August 2019 in Davao.
What course is LPU known for?
Many disciplines are taught in the university, with International relations (diplomacy, international trade), business, communication and International Hospitality (hotel and restaurant management, tourism) consistently being the university’s flagship courses.

What is mechanical pump?
Mechanical pumps generate vacuum by acting on the viscous properties of the gas or fluid being evacuated using mechanical devices such as pistons, claws, scrolling spirals, and diaphragms. Mechanical vacuum pump types are grouped by the technology or mechanism used.
Who invented turbopump?
Figure 1. The first turbopump developed and patented in 1957 by Dr. Willi Becker at Pfeiffer Vacuum. This chapter explains the most commonly used terms in vacuum technology and illustrates the principles involved.
What is a turbomolecular vacuum pump?
Turbomolecular pumps (TMPs) are kinetic vacuum pumps which operate using a very fast spinning rotor (usually rotating at between 24,000 and 90,000 RPM). Their typical operating pressures are in the high to ultra-high pressure range between 10–3 and 10–11 mbar, employing pumping speeds of between 10 and 4,000 l/s.
What is unit of vacuum?
Torr as units of measure are typically used for vacuums in the 1 to 760 Torr range. For measurements of vacuum on an even smaller scale, the “micron” is the term of use. One micron is equal to 0 . 001 Torr (10-3 Torr).
What is vacuum science?
A vacuum is a volume empty of matter, sometimes called ‘free-space’. In practice, only partial vacuums are possible.
What is torr vacuum?
Torr vacuum pressure unit
One torr (symbol: Torr) is approximately equal to one millimeter of mercury in a manometer at 0 °C. The unit micron can be found in the vacuum industry and its derived from the unit torr where one milliTorr is equal to one micron.
