Embibe Experts Solutions for Chapter: Fluid Mechanics, Exercise 1: Exercise-1

A beaker is completely filled with water at $4°\mathrm{C}.$ The water will overflow if it is :

For a fluid which is flowing steadily, the level in the vertical tubes is best represented by

Water flows through a frictionless duct with a cross-section varying as shown in fig. Pressure $p$ at points along the axis is represented by

The working of an atomizer depends upon

A large open tank has two holes in the wall. One is a square hole of side $L$ at a depth $y$ from the top and the other is a circular hole of radius $R$ at a depth $4y$ from the top. When the tank is completely filled with water, the quantities of water flowing out per second from both holes are the same. Then radius $R$ is equal to

Water is flowing inside a tube of an uniform radius ratio of radius of entry and exit terminals of the tube is $3:2$. Then the ratio of velocities at entry and exit terminals will be

The velocity of water flowing in a non-uniform tube is $20 \mathrm{cm} {\mathrm{s}}^{-1}$ at a point where the tube radius is $0.2 \mathrm{cm}$. The velocity at another point, where the radius is $0.1 \mathrm{cm}$ is

Water is poured in a vessel at a constant rate $\beta {\mathrm{m}}^3 {\mathrm{s}}^{-1}$. There is a small hole of the area $\alpha$ at the bottom of the vessel. The maximum level of water in the vessel is proportional to
