Define the basic barometer?
QUESTION: For an atmospheric pressure of 101 kPa (abs) determine the heights in meters of the fluid columns in barometers containing one of the following liquids: (a) mercury (SG = 13.55), (b) water, and (c) ethyl alcohol (SG = 0.79). Do these results support the widespread use of mercury for barometers? Why?
Capillary rise in the glass tube used for measuring water level isnot to exceed 0.5 mm. Determine its minimum size, given thatsurface tension for water in contact with air = 0.07112 N/m.
Q1 Determine the minimum size of glass tubing that can be used to measure water level, if the capillary rise in the tube is not to exceed 0.3 mm. Take surface tension of water in contact with air as 0.0735 N/m. A U-tube is made up of two capillaries of bores 1.2 m and 2.4 mm respectively. Q2) The tube is held vertical and partially filled liquid of surface tension 0.06 N/m and zero contact angle. If the estimated difference in the level of two menisci is 15 mm, determine the density the liquid. Q10) In measuring the unit energy of a mineral oil (specific gravity = 0.85) by the bubble method, a tube having an internal diameter of 1.5 mm is immersed to depth of 12.5 mm in oil. Air is forced through the tube forming a bubble at the lower end. What magnitude of the unit surface energy will be indicated by a maximum bubble pressure intensity of 150 N/m.
The liquid column height of a barometer is h = 733.74 mm, and the specific weight of the liquid is γ = 13.30 kN/m3. Calculate the atmospheric pressure, Patm____kPa
If the PO2 is 100 mm Hg at one barometric pressure (760 mm Hg), what is the approximate PO2 if the pressure is increased to 1,520 mm Hg in a hyperbaric chamber?
What will be the pressure head of a point in mm of Hg if pressure head of that point is equal to 63 cm of water? Assume specific gravity of H_{5} is equal to 13.6 and specific weight of water is 980N / (m ^ 2)
3. A barrel contains a 15 cm layer of oil of density 5.88 kN/m3 floating on water that is 30 cm deep. What is the gauge pressure in mmHg at the oil-water interface?
Pressure is often given in terms of a liquid column and is expressed as “pressure head.” Express the standard atmospheric pressure in terms of (a) mercury (SG = 13.6), (b) water (SG = 1.0), and (c) glycerin (SG = 1.26) columns. Explain why we usually use mercury in manometers
A manometer containing mercury with density, ρ = 13,600 kg/m3 is attached to a tank filled with air. The mercury-level difference between the two columns is 80 cm. Question i)With appropriate label to show both fluids and the depth difference, sketch a suitable diagram to visualize the system.
A barometer reads 765 mm of Mercury (g=13.6); what is the atmospheric pressure in N/m2.
