The relationship between the shear stress (V) and the rate of angular deformation of a fluid is
given by
The fluid with the exponent n > 1 is known as
A Bourdon gauge mounted on a closed pressurized container showing 65 KPa at Hyderabad where the atmospheric pressure is 100 KPa. If the container is now carried to a higher elevation (Ooty) where the atmospheric pressure is 90 KPa, what new reading will be shown by the bourdon gauge at Ooty?
The Bernoulli s equation is written with usual rotation as constant
In this equation each of the terms represents.
If a rectangular plate 4m x 3m is completely submerged under a fluid of relative density 0.8 as
shown in the given figure, then the hydraulic thrust on the plate would be, (Take g= 10m/s^{2} )
Figure shows a vertical contraction pipe carries water. The water diameter D_{2} for the condition of P_{1} = P_{2} ,in meters (Neglect losses ) is
The fluid entering a control volume has specific volume 0.833 m^{3}/kg and a velocity of 5 m/sec, the area of the intake being 20 cm^{2} . If the fluid leaves the control volume through a 25 mm diameter pipe with a velocity of4 m/sec, the mass flow rate (in kg/sec)
and fluid mass density (in kg/m^{3} ) respectively are:
A ram  jet rocket engine consumes 20 kg of air/sec and 0.6 kg of fuel/sec. The exit velocity of the gases is 520 m/sec relative to the engine and the rocket velocity is 200 m/sec absolute. What is the nearly momentum power developed?
A pitot  static tube is used to measure air velocity. If a manometer connected to the instrument indicates a difference in pressure head between the tappings of 4 mm of water, calculate the air velocity assuming the coefficient of the pitot tube to be unity. Take density of air = 1.2 kg/m^{3 }and g = 9.8 m/sec^{2} .
The velocity of air is ____ m/sec . ?
Water is pumped through a pipe line to a height of 10 m at the rate of 6000 l.p.m, Friction and minor losses are 5m, then the power of pump required is ____ (in KW)
(Take g=10m/s^{2})
In an automobile traveling at ‘V’ kmph the power expended in over coming resistance is T. If the automobile travels at ‘3 V’ kmph the power expended in over coming wind resistance is,
Water is flowing through a horizontal pipe of constant diameter and the flow is laminar. If the diameter of the pipe is increased by 50% keeping the volume flowrate constant, them the pressure drop in the pipe due to friction will decrease by
The head loss in 100 m length of a 0.1 m dia. pipe (f = 0.02) carrying water is 10 m. The boundary shear stress in kPa
