Fluid Flows

An incompressible fluid flows steadily through a cylinder pipe which has radius 2 R at point A and radius R at point B further along the flow direction. IF the velocity at point A is v, its velocity at a point B will be

Assertion : When an ideal fluid flows through a pipe of non-uniform cross-section, then pressure is more at that section where area is more if the pipe is horizontal. Reason : According to Bernoulli's theorem speed at broader cross-section will be less.

A non-viscous liquid of constant density 500 kg//m^(3) flows in a variable cross-sectional tube. The area of cross section of the tube at two points P and Q at heights of 3 m and 6 m are 2 xx 10^(-3) m^(3) and 4 xx 10^(-3) m^(3) , respectively. Find the work done per unit volume by the forces of gravity as the fluid flows from point P to Q .

A non-viscous liquid of constant density 1000kg//m^3 flows in a streamline motion along a tube of variable cross section. The tube is kept inclined in the vertical plane as shown in Figure. The area of cross section of the tube two point P and Q at heights of 2 metres and 5 metres are respectively 4xx10^-3m^2 and 8xx10^-3m^2 . The velocity of the liquid at point P is 1m//s . Find the work done per unit volume by the pressure and the gravity forces as the fluid flows from point P to Q.

Explain why a fluid flowing out of a small hole in a vessel results in a backward thrust on the vessel.

Figure shows an ideal fluid flowing through a uniform cross-sectional tube in the vertical tube with liquid velocities v_(A) and v_(B) and pressure P_(A) and P_(B) . Knowing that offers no resistance to fluid flow then which of the following is true.

An incompressible liquid flows through a horizontal tube as shown in the figure. Then the velocity 'v' of the fluid is:

Fluid mosaic model was proposed by:-

A portion of a tube is shown in the figure. Fluid is flowing from cross-section area A_(1) to A_(2) . The two cross-sections are at distance 'l' from each other. The velocity of the fluid at section A_(2) is sqrt((gl)/(2)) . If the pressures at A_(1) & A_(2) are same, then the angle made by the tube with the horizontal will be:

The pressure of an imcompressible & non - viscous fluid also depends upon the velocity of flow at that point .
