 Unless mentioned, the following values of fluid characteristics can be used when ever necesarry in solving the questions. water= 1 t/m3, mercury= 13.6 t/m3 ve patm=1 kgf /cm2 are used.

Question 1: Find the absolute and gage pressures at the point A in the U manometer given below.

End of the tube is open to atmosphere.

Question 2: In the manometer system given below, the absolute pressure of the enclosed gas is Pgaz

= 39.24 kN/m2. Find the horizontal distance X.(yağ=7.85 kN/m3).

Question 3: For the given values of d1=30 cm, d3=45 cm, d4=20 cm, find the pressure difference between points A and B given in the drawing below.

Question 4: Taking into consideration the manometer system shown below find the absolute

pressure at point A. (patm=101.34 kN/m2, glycerin=12.36 kN /m3, water=9.81kN /m3)
