How do you calculate the liquid pressure?
By using a device called manometers.
What is the relationship between liquid pressure and the depth of a liquid between liquid pressure and density?
pressure of liquid on bottom=density*gravitational force*depth :)
Does refrigerant enter the compressor as a low temperature low pressure gas?
Yes. The basic components of the refrigeration system are the refrigerant, compressor, condenser and receiver, expansion device and the evaporator. One cycle: Refrigerant travels to Compressor (A) to Condenser (B) to Expansion device (C) to evaporator (D). The refrigerant gas at low pressure and temperature is drawn into the compressor. The gas is compressed to a higher pressure, which causes an increase in the temperature. The refrigerant gas at a high pressure and temperature passes to the condenser (point B), where it is cooled (the refrigerant gives up its latent heat) and then condenses to a liquid. The high pressure, low temperature liquid is collected in the receiver. The high pressure liquid is routed through an expansion valve (point C), where it undergoes an abrupt reduction in pressure. That pressure reduction causes part of the liquid to immediately vaporize or flash. The vapor and remaining liquid are cooled to the saturation temperature (boiling point) of the liquid at the reduced pressure. At this point most of the refrigerant is a liquid. The boiling point of the liquid is low, due to the low pressure. When the liquid refrigerant enters the evaporator (point D), it absorbs heat from the process and boils. The refrigerant gas is now at low pressure and temperature, and enters the suction side of the compressor, completing the cycle.
Is the compressed liquid has the same meaning to saturated liquid?
No - compressed liquid is at a pressure above the boiling point pressure of the liquid. A saturated liquid is right at that boiling point. If you try to drop the pressure on a saturated liquid, it will begin to boil. If you start dropping the pressue on a compressed liquid, it will remail a stable liquid unit you have dropped it to the saturation pressure.
What can a boil be defined as?
Boiling, a type of phase transition, is the rapid vaporization of a liquid, which typically occurs when a liquid is heated to its boiling point, the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environmental pressure.
What device can use atmospheric pressure to move a liquid from one side of a pile of rocks to another?
siphon
What is the refrigerants state when entering the metering device?
High pressure liquid
What component of a refrigeration system changes a high pressure vapor to a high pressure liquid?
Metering device
How do you calculate the liquid pressure?
By using a device called manometers.
What AC component changes high liquid pressure to low liquid pressure?
The metering device. Depending on what type of system you have, this will either be a Fixed Orifice Tube or it will be a Thermal Expansion Valve.
What is an orifice meter?
A device for measuring the flow of a liquid.
What is a hydraulic device?
machine that takes advantage of the fact that pressure is sorted out equally in all directions possible in a liquid. :)
The operation of a hydraulic device can be explained in terms of?
The principal is called Pascal's Principle. Pascal's principle states that a pressure applied to an enclosed fluid is transmitted everywhere in the fluid. Hence, if a pressure is applied to one side of an enclosed fluid, all the other walls containing the fluid feel the same pressure. The pressure is transmitted without being diminished. Fluid generally refers to either a liquid or a gas. If a pressure is applied to a compressible gas, Pascal's principle still applies, but the volume of the gas will change. For Pascal's principle to be useful to hydraulics, the fluid should be an incompressible liquid, which will transmit the applied pressure without changing its volume.
What is the relationship between liquid pressure and the depth of a liquid between liquid pressure and density?
pressure of liquid on bottom=density*gravitational force*depth :)

When the vapor pressure of a liquid equals the air pressure in the room what will the liquid do?
The liquid starts boiling
What is the cause of liquid pressure?
The weight of the liquid is, plus possibly the atmospheric pressure on the top surface of the liquid.
