Answer 2

The appropriate fluid flows into a pipe kept in a horizontal position as shown in the figure and the flow is normal flow, pressure at two points is shown, are:

• Flow the appropriate fluid (laminar flow) through a pipe of different diameters.

• The minimum size and diameter of the pipes is 6.4 cm and 4.8 cm, respectively.

• The minimum velocity and maximum volume of liquid in this pipe is a. √ (3/2).

• In the case of a streamline flow, the tangent drawn at any point of the curve (path) will correspond to the flow velocity at that point.
• The diagram below represents a curve with tangent in different directions.
• It describes how particles in a liquid move with respect to time.

• The pressure in point 2 is equal to the pressure in position 3.

• Note that the length should be in meters.

• The pressure in point 4 is the same as that in point 5, as the air pressure is relatively low compared to that of oil.
• Pressure difference between the two pipes using readings on the manometer.
• Use Soil = 0.85 and S Hg = 13.6 Solution.
• Interesting points are placed on the manometer.
