Water flows downward in a pipe at 45°, as shown inFig. P2.44. The pressure drop p, – P2 is partly due to gravityand partly due to friction. The mercury manometer reads a6-in height difference. What is the total pressure drop p, - P2in Ibf/in?? What is the pressure drop due to friction onlybetween 1 and 2 in Ibf/in? Does the manometer readingcorrespond only to friction drop? Why?455 ftFlowWater6 inMercuryP2.44

If a closed tank contains compressed air and oil (SGoil = 0.90), with a U-tube manometer using mercury (SGHg = 13.6), is connected to the tank as shown in the figure below. For column heights h1=1 m, h2= 25 cm, and h3= 245mm then the pressure exerted on the system by the mercury is kPa Air Cil Pressure gage (1) Open (2) H₂
Consider the manometer tube shown in below Figure 1. It is filled with three differentincompressible fluids. The closed end of the tube is connected to a reservoir with aconstant pressure. For this configuration, calculate i) the pressure in the reservoir in kPa, ii) the pressure in the reservoir as gage pressure in kPa, iii) the equivalent height of water, and iv) the equivalent height of mercury.
A special tyre was inflated at 2 bar gage pressure on Earth, where the atmospheric pressurewas 1013 hPa and the acceleration of gravity 9.81 m/s2.The tyre was then transported without pressure leakage on Mars, where the atmosphericpressure was 6 mbar and the acceleration of gravity 3.7 m/s 2.Questions:(a) Measuring on Earth the tyre pressure with a mercury manometer, what was themanometer reading in mm?(b) Measuring on Mars the tyre pressure with a mercury manometer, what was themanometer reading in mm?
