Streamline Flow

A common application of laminar flow is in the smooth flow of a viscous liquid through a tube or pipe.

What is streamline? What are its properties?

The laminar flow of a fluid can be described as the flow of parallel streamlines.

In laminar flow of a fluid:

Here we know that for turbulent flow, we need a certain limit of Reynolds number. So, what is Reynold's number?

Rather than higher velocity of the flow, starting the turbulent is depends on _____.

For starting turbulent, we need low velocity flow.

What is reynolds number condition for starting the turbulent?

Streamline flow is more likely for liquids with _____ (low density/high density) and high viscosity.

Stream line flow of a liquid at a given point.

Define streamline flow.

What is streamline flow?

Water is moving with a speed of $5.18 \mathrm{m} {\mathrm{s}}^{-1}$ through a pipe with a cross-sectional area of $4.20 {\mathrm{cm}}^2$. The water gradually descends $9.66 \mathrm{m}$ as the pipe increases in area to $7.60 {\mathrm{cm}}^2$. The speed of flow at the lower level is

A stream of water flowing horizontally with a speed of $15\mathrm{ }\mathrm{m} {\mathrm{s}}^{-1}$ gushes out of a tube of cross-sectional area ${10}^{-2} {\mathrm{m}}^2$ and hits a vertical wall normally. Assuming that it does not rebound from the wall, the force exerted on the wall by the impact of water is:

A container has a hole at the bottom of area $1 c{m}^2.$ Liquid is being added at the rate ${10}^{-4}{m}^3/s$ into it so that height of liquid in container remains constant. The height of liquid in container at equilibrium is

Water is flowing through a tube of non-uniform cross-section. If the radii of the tube at the entrance and exit are in the ratio $3\mathrm{ }:2$, then the ratio of the velocity of liquid entering and leaving the tube is

Blood is flowing at the rate of $100\mathrm{ }{\mathrm{cm}}^3 {\mathrm{s}}^{-1}$ in a capillary of cross-sectional area $0.25\mathrm{ }{\mathrm{m}}^2$. The velocity of flow is 

A massless container is filled with liquid of density $\mathrm{\rho }$. It contains two holes as shown in figure. Container rests on ground. Area of the two holes are $\mathrm{A}$ each. Container is filled with liquid upto height $\mathrm{H}$. Then -

Water is flowing in a pipe of diameter 4 cm with a velocity $3 {\mathrm{m}\mathrm{s}}^{-1}$. The water then enters in to a pipe of diameter 2 cm. the velocity of water in the other pipe is

Water is moving with a speed of $5.18 \mathrm{m} {\mathrm{s}}^{-1}$ through a pipe with a cross-sectional area of $4.20 {\mathrm{cm}}^2$. The water gradually descends $9.66 \mathrm{m}$ as the pipe increases in area to $7.60 {\mathrm{cm}}^2$. The speed of flow at the lower level is
