PROBLEM SHEET Intro Lab Problem - Manometers Group Nou Nams 1. Provide the following two sketches the dimension your sketches Cooler experiment. Make sure to cl 31h 17 in Riso P2 = PATM + hd-hadz-hats P2-PATm-ho 83 • (a) Actual Water Cooler Test Setup (b) Equivalent Simple Manometer 2. Calculate the unknown pressure(s). expressing your answer in both absolute and page pressures P2=PATm-h383. 0-(131) 160361) P2 = -6.47291 Psil P2=PATm-hatz = -0.47291 Psi ) gage Pressure = -0.4 7291 +17. -> Absolute - 14.2269 PS na 3. Assume that you made your measurements on a nice sunny day. Then assume that you repeated the same measurement on a rainy day. Would anything change? Explain why or why not answer on the reverse side of this sheet).

Answer 1

Gauge pressure. Atmospheric Pressure Pressure Vaccume pressure. 4 Absolute Pressure Absolute vacuum + + Absolute pressure :- It is the pressure measured from absolute vaccum Gauge pressure :- The pressure measured with measuring instruments. å above atmospheric pressure It → Vaccum pressure :- It is the negative pressure or the pressure measured below atmospheric pressure → Atmospheric pressure :- It u the pressure in the surroundi. atmosphere rainy Incase of a mang day the atmospheric pressure would fau from the level that it used to be during the sunny days, Hence the absolute pressure not change as it has a fixed point of reference but the gauge pressure would change as it is measured from the level of atmosphene pressure.
