Whois & Analysis for masterbuildermercantile.com

Plumbing is any system that conveys fluids for a wide range of applications.

Plumbing uses pipes, valves, plumbing fixtures, tanks, and other apparatuses to convey fluids.

Heating and cooling (HVAC), waste removal, and potable water delivery are among the most common uses for plumbing, but it is not limited to these applications.

The word derives from the Latin for lead, plumbum, as the first effective pipes used in the Roman era were lead pipes.

Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space.

Its goal is to provide thermal comfort and acceptable indoor air quality.

HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer.

"Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers).

Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge.

Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations.

Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others.

Retail is the sale of goods and services to consumers, in contrast to wholesaling, which is sale to business or institutional customers.

A retailer purchases goods in large quantities from manufacturers, directly or through a wholesaler, and then sells in smaller quantities to consumers for a profit.

Retailers are the final link in the supply chain from producers to consumers.

The ampere (symbol: A), often shortened to amp, is the unit of electric current in the International System of Units (SI).

One ampere is equal to 1 coulomb (C) moving past a point in 1 second.

It is named after French mathematician and physicist André-Marie Ampère (1775–1836), considered the father of electromagnetism along with Danish physicist Hans Christian Ørsted.
