The flow of blood in a larger artery of an anesthetised dog is diverted through a venturimeter. The wider part of the meter has a cross-sectional area equal to that of the artery, a1 = 8mm2. The narrow part has an area a2 = 4mm2. The pressure drop in the artery is 24 Pa. What is the speed of the blood in the artery?

A fully loaded Boeing aircraft has a mass of 3.3\(\times \)10⁵ kg. Its total wing area is 500 m². It is in level flight with a speed of 960 km/h
Estimate the fractional increase in the speed of the air on the upper surface of the wing relative to the lower surface.[The density of air is \(\rho \)= 1.2 kgm^-3

Near the surface of the river, the velocity of water is 160 kmh ^-1 .Find the shearing stress between horizontal layers of waters, if the river is 6 m deep and the coefficient of viscosity of water is 10^-2 poise.

If 27 drops of rain were to be combine to form one new large spherical drop, then what should be the velocity of this large spherical drop? Consider the terminal velocity of 27 drops of equal size falling through the air is 0.20 ms^-1

The flow rate of water is 0.58 L/mm from a tap of diameter of 1.30 cm. After some times, the flow rate is increased to 4 L/min. Determine the nature of the flow for both the flow rates. The coefficient of visocity of water is 10^-3 Pa-s and the density of water is 10³ kg/m³.

A liquid is kept in cylindrical vessel which is rotated along its axis. The liquid rises at the sides. If the radius of vessel is 0.05 m and the speed of rotation is 2 rev/s, find the difference in height of the liquid at the centre of the vessel and its sides.

Water flows through a horizontal pipe whose internal diameter is 2.0 cm , at speed of 1.0 ms^-1 . What should be the diameter of the nozzle, if the water is to emerge at a speed of 4.0 ms^-1 ?

Derive the expression for excess pressure inside:
(a) a liquid drop
(b) a liquid bubble
(c) an air bubble.

State law of floatation.
Compute the volume in m³ of a life preserver of SG 0.20, which, when worn by a boy.weighing 60 kg and having SG equal to 0.9, will just support him, if 3/4 of his body is submerged in fresh water of density 1000 kg m^-3. Assume that the life preserver is completely submerged.

What are the three forms of energy possessed by a flowing fluid? Find their expressions.

Water stands at a depth H in a tank, whose side walls are vertical. A hole is made on one of the walls at a depth h below the water surface. Find at what distance from the foot of the wall does the emerging stream of water strike the floor and for what value of h this range is maximum.
