Question 2
A streamline and an equipotential line in a flow field
Question 3
A spherical water droplet of 1.2 mm in diameter splits in air into 60 smaller droplets of equal size. Find the work in micro Joule required in splitting up the droplet. The surface tension of water in air is 0.073 N/m.
Question 4
Consider the U-tube differential manometer as shown in the figure. The magnitude of pressure difference between point A and point B (in kPa) will be
Question 5
A venturimeter of dimension 25cm and 10cm is used to measure the flow of water. The pressure at inlet is 16.254 N/
and at the throat is vacuum pressure of 40cm of mercury. Taking coefficient of discharge = 0.98, calculate the discharge (
)
and at the throat is vacuum pressure of 40cm of mercury. Taking coefficient of discharge = 0.98, calculate the discharge ()Question 6
A horizontal venturimeter of throat diameter 0.25 m is used to measure the flow of oil of specific gravity 0.9.The discharge of oil through main pipe (dia= 0.5m) is 100L/s. Find the reading of the oil-mercury (sp. gr. 13.6) differential manometer (in mm). Take the coefficient of discharge as unity.
