Q1) Water and oil in horizontal pipelines. A double
U-Tube manometer is connected between the
pipelines as shown in figure. Calculate the pressure
difference between the water pipe and oil pipe. (sp.gr
for liquid and oil are 1.6 and 0.9 respectivelly)
Q2) The system in Fig. is at 20°C. If atmospheric pressure
is 101.33 kPa and the pressure at the bottom of the
tank is 242 kPa, what is the specific gravity of fluid X?
Q3) a-What is the pressure of oil shown in figure if the pressure
in the water pip?
b- If the pressure increased to 15.5 kPa, while the pressure in the
oil pipe remain constant. What will be the new
manometer reading?
Q4) For the tank shown in the figure, determine the
reading of pressure gage if h=10cm and
H=2m.
Q5) A mercury U-tube manometer is used to measure the pressure drop across an
orifice in pipe. If the liquid that flowing through the orifice is brine of sp.gr.
1.26 and upstream pressure is 2 psig and the downstream pressure is (10 in
Hg) vacuum, find the reading of manometer.
