A U-tube manometer containing mercury has its right limb open to atmosphere. The lett limb is full of water and is connected to a pipe containing water under pressure, the center of which is in level with the free surface of mercury Find the pressure of the water in the pipe above atmosphere, if the difference of level of mercury in the limbs is 5.08 cm.

A well-type inclined manometer has a gas pressure difference of 17 cm-of-water at its ports (higher pressure to well). If the manometer is inclined at an angle of 12 degrees and contains water, what is the reading on the manometer (i.e. R)?

Atmospheric pressure is 1 atm. Find pressure of gas in terms of atm; If system is closed manometer, and the height of the fluid column on the gas side is 20 mm, and that on the other side is 210 mm

The Tainter gate, shown in the .gure, is a circular arc ABC. It is raised and lowered by pivoting about point O. Water B R Part A: Find the net force due to pressure (horizontal and vertical components) acting on the gate. The pressure on the right side of the gate is patm. Let R = 4 m and the width of the gate be equal to R. Part B: Find the center of pressure. Show that the force acts through point O. Part D: Explain why this type of gate would close automatically under its own weight in the event of mechanical failure of whatever mechanism rotates the gate about O.

3. A mercury barometer at the base of Mt. Makiling reads 654 mm and at the same time another barometer at the top of the mounta in reads 480 mm Assuming specific weight of air to be constant at 12 N/m', what is the approximate height of Mt. Makiling?

B2.    An oil of specific gravity 0.88 is flowing through the pipe of diameter 30cm.  one end of the simple U tube manometer contains mercury, is inserted  with the center of pipe and other end is open to atmosphere.  The level difference in mercury is found in the left limb as 36 cm.  The distance between the center of the pipe and the mercury level is 14 cm.  Find the pressure of oil in the pipe in kPa.  Draw the diagram neatly. (Enter only the values by referring the unit given.  Also upload the hand written answers in the link provided) The pressure of oil in the pipe (in kPa)                           Answer

A micircular gate with a radius R = 5 ft is hinged along B and held by a horizontal force applied at A. The picture on the right shows the gate if you were looking in the direon of the arrow beneath FA. The liquid has a depth of H=40 ft and applies a force on the ate of 200,032 lbf. What is FA in Ibf? FA A Gate: side view

4. The right limb of a simple U-tube manometer containing mercury is open to the atmosphere while the left limb is connected to a pipe in which a fluid of sp.gravity 0.9 is flowing. The centre of the pipe is 12 cm below the level of mercury in the right limb. Find the pressure of fluid in the pipe if the difference of mercury level in the two limb is 20 cm . And also draw the arrangements.

A manometer showed in Fig. 1 (right) connects pipe A and pipe B. It reaches a balance at the showing state. Determine a) When the pressure in pipe A is increased from the current state by 32 kPa while the pressure in pipe B remains constant, the interface between water and mercury in the left leg of the manometer will go up or down? b) Calculate the change in the elevation of this interface.
