A mercury (Hg) manometer is used to measure the pressure in a vessel as shown below. The mercury has a density of 13590 kg/m3, and the height difference between the two columns is measured to be 24cm. We want to determine the pressure inside the vessel.

A container filled with water and there are two holes, as shown in figure below. What is the ratio of x1 to x2? 20 cm 100 am 50 cmB X1 X2 13. Given frictionless flow of water at 125.6 ft'/s in a long, horizontal, conical pipe of diameter 2ft at one end and 6ft at the other. The pressure head at the smaller end is 18ft of water. Find the velocities at two ends and the pressure head at the larger end.

The plug has a diameter of 30 mm and fits within a rigid sleeve having an inner diameter of 32 mm. Both the plug and the sleeve are 50 mm long. The plug is made from a material for which E= 1 MPa, v=0.7. (Figure 1) Figure Part A Determine the axial pressure p that must be applied to the top of the plug to cause it to contact the sides of the sleeve.

A liquid-filled tube called a manometer can be used to measure the pressure inside a container by comparing it to the atmospheric pressure and measuring the height of the liquid. Such a device (filled with water) is shown in the figure, measuring the pressure inside a balloon filled with an unknown gas. The water level on the side of the manometer which is open to the air is 22.3 cm higher than on the side connected to the balloon. a) Find the gauge pressure in the balloon, in units of Pa. Recall the density of water is 1000 kg/m3.  b) Find the absolute pressure in the balloon, in units of Pa.
