Question 1

A body weight 100 N and 70 N in air and water respectively. the density of body will be

Question 2

The velocity field in a fluid medium is given by V = 2xy î + 2xy2 ĵ + 3zt k̂. Find the magnitude of rotational velocity vector at (2, 1, 1) and t = 2.

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 ()

Question 6

Water flows through a circular pipe of 60 cm diameter at a flow rate of 500 litres/sec. Pipe was connected with a nozzle whose exit diameter is 30 cm into the atmosphere. Neglecting losses and hydrostatic force the force exerted by water on the nozzle (in N) is
