What is the unit of density for liquid?
Density unit is mass / volume. SI unit for dendity is kg/m3.
What unit is used to label liquid volume?
The unit or label to measure liquid volume is ml (milliliters)
How many gallons are in 61.7 pounds?
The estimate would be just under 8 gallons. Pounds is a unit of mass/weight. Gallons is a liquid measure. They do not convert cleanly. The density of the liquid being measured can make a big difference. If the liquid is water, there is 8 pounds to a gallon.
What is latent heat of fusion of a solid?
It is the amount of heat (measured in the proper unit, say calories) required to change a unit mass (measured in the proper units, say gram) of a substance from the solid to the liquid state. This would also be the heat given out by a unit mass of the liquid when it changes to the solid state.
How do you measure fre-on?
On smaller residential air conditioners the manufacturer publishes a charging chart that has the outside air temperature and the corresponding suction and liquid pressure measured by a refrigeration manifold set, gauges. If the chart is not available, you can estimate by measuring the suction pressure and then using a pressure temperature chart for your refrigerant and trying to maintain a 35 degree to 40 degree temperature at the condensing unit or compressor. The other measurement on larger units is the subcooling measurement, measure the actual liquid line temperature and compare the liquid pressure using a pressure temperature chart and also checking for bubbles in the liquid line sight glass. On larger systems after the subcooling has been checked then the superheat has to be checked and the thermostatic expansion valve adjusted if necessary. To check the superheat, measure the suction pressure, convert to a temperature and then measure the actual suction line temperature. The difference is the superheat, should be 6 to 20 degrees depending on the system.
What is the liquid line and suction line?
The suction line is the big one. This line should be cold when the unit is on. The small line is the liquid line.
Should the liquid line of an ac unit be cool?
No, the "liquid line" is the little line, also called the "high side" line. When operating properly, it should be hot, sometimes very hot.
How far should oil-trap has to be from 20 ton ac unit?
Half way between the the condenser and air handler, in the liquid line.
What two copper lines connect the evaporator section with the condensing unit?
suction line liquid line
At microwave frequency why should the transmission line may considered to be made of unit length?
at microwave frequency why should the transmission line may considered to be made of unit length?
What unit would you use to measure a the liquid in a dropper?
millileter (ml) should be appropriate for that.
What is the correct procedure for a pump down?
With the unit running, front seat the liquid line valve and monitor the pressure. Once you have the unit in a vacuum, front seat the suction side and cut the power to the unit.
What is the SI unit of liquid volume?
Milliliters is the SI unit of a liquid volume
What unit is the volume of a liquid measured in?
litrer is the unit for liquid in metric system. and cubic meter in SI unit.
How do you remove a clog without losing all freon from the thin copper tube on the low pressure side of a split AC that is frozen for 10 inches then a couple of fittings and it is warm from there on?
There should be a pump down valve at the condenser. One for the suction and one for the liquid side. Simply front seat the valve on the liquid line and wait for the unit to pump down, then front seat the suction side and cut the pipe and replace. You may want to install a liquid line dryer before you evacuate the system and recharge the unit.
What large line unit connects the indoor unit to the out door unit?
Discharge line
What unit for volume would you use for a liquid?
the unit for volume, for a liquid would be oz(ounces) I believe..
