The objective of this lab is to help the student gain a deeper understanding of the differentpressure measuring devices that are frequently used. Also the students will learn how to calibratea pressure gage that is directly attached to a water tank.IntroductionWhen designing, or working with a part it is of extreme importance to know the pressurethat there is in the system. This is because it helps us understand the flow of the liquid that themachinery has and even if a critical limit is being reached. Since the pressure inside the systemcan vary at different points, it is also important to measure the pressure at different locations. Forpneumatic and hydraulic pressure, universally bourdon tube gages most commonly used withexception to when there is a very low pressure in the range of 0-5psi. For this, liquid filledmanometers are more common. This is because other than being sensitive to low pressure, it doesnot require any calibration.The way manometers measure pressure is by measuring the height difference of the substance itcontents. Once pressure is applied on one leg of the tube, the pressure forces the liquid up anddown on the other leg. That said, the height difference of the two columns determines what theright amount of pressure is beingexposed to. There is also a well-type manometer. In contrast,this manometer uses a single tube that contains a confined liquid at the end of it. Once pressure isadded, this liquid will increase in height or decrease. So instead of reading the differencebetween two tubes in the U-tube manometer, one only has to read one.Since mercury has a
