- 6 Compressed gas tanks often have gage pressures of at least 1 MPa. Suppose you wished to use a manometer to measure the gage pressure of a compressed air tank whose pressure was at least 1 MPa. The manometer would be set up between the tank and the atmosphere. What is the minimum length of tube needed for such a measurement if the liquid in the manometer is (a) mercury (p = 13,500 kg/m² ), (b) water (p = 1000 kg/m³ ), and (c) engine oil (p = 880 kg/m2 )? Do these seem to be practical devices for such a measurement?arrow_forward.ll GH Vodafone LTE 6:38 AM © 85% 4 Today Edit 6:36 AM .ll GH Vodafone LTE 6:36 AM @ 84% 4 MCE 243 Note New.pdf Question 3 A multi-fluid container is connected to a U-tube manometer as shown in fig below.
