Task 3:Your work is to study the following well-type manometer that will be used for students in the fluidmechanics lab:The manometer is built with a tube diameter of 20 mm and a reservoir diameter of 10 cm. Whenthere is no pressure difference across the manometer, the elevations on both sides are the same atA* level.
1. When a high pressure is applied to the left side, the water in the small tube goes 30 cm up,calculate PA.2. Explain the use and limitations of manometers. Then suggest two points for using welltype manometer for accurate measurements, write your answer in 75 words or less.
A tube 5 m long is inclined at an angle of 75° with the horizontal. If It is filled with water, Calculate
pressure at its bottom.
A small pipe 0.60 m long is filled with water and caped ar its end. It is placed in a horizontal position.
a. How fast must it be rotated about a vertical axis 0.30 m from one end to produce a maximum pressure of 6.895 Kpa?
b. What is the pressure at the other end of the pipe?

The bottom of the tank (elevation 1030 m) connects to an outlet pipe (diameter 1/2 m) for supplying water to the water main (elevation 990 m). According to the local guidelines, pressure at any point along the water main must be between 30 and 60 psi (including the junction point with the outlet pipe).
