What Size Air Conditioner Do You Need . If you have a lot of very sunny rooms you’re cooling, you may need an air conditioner that is 10% larger than the square footage/btu indicators recommend. Generally, in australia you will need 120 to 150 watt of power per square meter of floor area. What Air Conditioner Size Do I Need 5 Best Suggestions from homegearslab.com As such, you need a properly sized air conditioner, one that is suitable for your needs. Consumer reports recommends 20 btus per square foot of the living space (or spaces) you want to cool down. As a rule of thumb, the maximum ac unit size you need to install should not be more than 15% more than the btu’s you need to cool your house.
Calibration Of Bourdon Tube Pressure Gauge Using Dead Weight Tester
Calibration Of Bourdon Tube Pressure Gauge Using Dead Weight Tester. This dead weight tester uses a simple piston and cylinder arrangement to provide a source of pressurized liquid (in the experiment water will produced a better result than oil) which is transmitted to the gauge. A flexible tube containing water transfers the pressure on the piston to the bourdon tube.

Figure 1 dead weight calibrator objective to calibrate a bourdon type pressure gage and determine the gage errors. Pressure = force/area = w/a. Calibration of pressure gauge aim:
Master Equipment’s Required For Performing Calibration:
The main purpose for doing this experiment is to fulfill pressure calibration on a bourdon tube pressure gauge using a dead weight tester. The dead weight pressure calibration system consists of a piston and a cylinder. The piston has a known area, so students can calculate the pressure.
Anubhav Shah On Displacer Level Transmitter Calibration Using Water & Process Liquid;
To calibrate the gauge, students add weights to a platform on a dead weight tester. Normal calibration procedure is to load the gauge with known pressures, using a dead weioht tester using oil. A bourdon gauge is supplied for calibration.
In The Present Investigation, We Have Studied Dead Weight Tester To Calibrate Bourdan Type Pressure Gauge, After Experimental Work It Is Found That The Gauge Is Giving Better Result At Lower Reading And As We Increase Weight The Gauge Reading Seems To Give Significant Changes In The Result With Respect To Actual Pressure
The piston has a known area, so students can calculate the pressure. A dead weight calibrator uses known weights to apply pressure to a fluid for checking the accuracy of readings from a pressure gage. It is the process of configuring an instrument to provide results within an acceptable range.
The Weights Will Be Added To The Upper End Of The Piston Rod.
A deadweight pressure gage is the most accurate pressure gauge which is generally used for the calibration of other pressure gauge apparatus in field and laboratories. A flexible tube containing water transfers the pressure on the piston to the bourdon tube. Description of apparatus the bourdon pressure gauge shown in fio 3.1 has a transparent dial through which the construction may be viewed.
The Present Experiment, However, Works Satisfactorily With Oil.
A bourdon gauge is supplied for calibration. Deadweight tester or hydraulic deadweight tester is a bench use reference standard for calibrating pressure gauges. Calibration of pressure gauge aim:
