|
what is a open hydronic system
A hydronic system that is, at some point, open to the atmosphere.
|
what is atmospheric pressure
The force exerted by the weight of the atmosphere (gas molecules) on the Earth's surface.
|
what is a rotary pump
A pump that utilizes a rotary motion that carries the fluid from the suction to the discharge port.
|
what is a human-machine interface (HMI)
An interface terminal that allows an individual to access and respond to building control system information.
|
who are the baltimore ravens baby!!!!
nfl team that will win the super bowl in 2019
|
|
what is a hydronic system
A heating and/or cooling system that uses water or another fluid as a heat transfer medium to move heat from one area to another.
|
what is specific heat
The amount of heat in British thermal units required to change the temperature of one pound of a substance one degree Fahrenheit.
|
what is a pump
A device through which an external source of power is used to apply a force to a fluid in order to move the fluid from one place to another.
|
what is a solenoid
A device that converts electrical energy into a linear mechanical force.
|
who is ray lewis (who else)
greatest linebacker of all time
|
|
what is a hypocaust
A heating system utilizing a raised floor set on stacks of tiles called pilae for heat transfer.
|
what is a thermometer
Any instrument used to measure temperature.
|
what is a gate valve
A full-way valve used to regulate fluid flow in which a threaded stem raises and lowers a wedge-shaped disc that fits against a smooth, machined surface, or valve seat, within the valve body.
|
what is a controller
A device that makes decisions to change some aspect of a system based on input variables (sensor information) and internal programming.
|
do you even have to ask!!
what team beat denver in the 2012 playoffs and eventually won the super bowl that year
|
|
closed hydronic system
A hydronic system that is not open to the atmosphere
|
what is a change of state
The change that occurs when a substance changes from a solid to a liquid, from a liquid to a vapor, or vice versa.
|
what is a ball valve
A valve in which fluid flow is controlled by a ball that fits tightly against a resilient (pliable) seat in the valve body.
|
what is a temperature sensor
A sensor that measures the temperature of air or a liquid.
|
again, do you have to ask
will joe flacco take denver to the super bowl this year?
|
|
who was the greatest quarterback of all time
John Unitas
|
what is boiling point
The temperature at which, upon absorption of sufficient heat, a liquid will change to a gas or vapor. For any given substance, the temperature at which this occurs depends on the pressure being exerted on the substance; the higher the pressure, the higher the boiling point.
|
what is an impeller
The rotating element inside the volute of a centrifugal pump that applies energy to the HTF.
|
what is a transducer
A device that converts one form of energy into another.
|
who is john elway
