A venturimeter is `37.5 cm`. Diameter in mains and `15 cm`. Diameter in throat. The difference between the pressure of water in the mais and the throat is `23 cm` of Hg. Find the discharge in `litres//minunte`. Sp. Gravity of Hg. `13.56`.

The difference between circumference and diameter of circle is 30cm, find the radius of circle.

A venturimeter has a threat of diameter 0-06 m. The diameter of the horizontal pipeline where the venturimeter is inserted is 0-1 m. The pressure difference between the mainline and the throat is 0-32 of water. Calculate the rate of now of water in the pipeline. ?

The diameter of the throat of a venturimeter is 6 cm .when it is inserted in a horizontal pipe line of diameter 10 cm the pressure difference between the pipe and the thraot equal 8 cm of water . Calulate the rate of flow.

A pitot tube is connected to a main pipeline of diameter 16 cm. The difference in height of the water columns in the two arms of the tube is 10 cm. Determine the rate of flow of water through the main pipe.

Calculate the discharge in litres per minute of a venturi-meter if it is of 86 cm diameter in main part and of 10 cm diameter in neck part. Specific gravity of Hg=13.6 and difference of pressure of water between mains and neck is 20 cm of Hg.

A pitot tube is fixed in a main pipe of diameter 20 cm and difference of pressure indicated by the gauge is 5 cm of water column. Find the volumn of water passing through the main pipe in one minute.

A pipe is running full of water. At a certain point A It tapers from 60 cm diameter to 20 cm at B. The pressure difference between A and B is 1 m of water column. Find the rate of flow of water through the pipe.

The difference between Circumference of circle A and diameter is 60 cm. If Radius of Circle Bis 6 cm less than circle A then find area of Circle B?
