FLOW OF LIQUID IN A TUBE: CRITICAL VELOCITY

In the figure, an ideal liquid flows through the tube, which is of uniform cross section. The liquid has velocities v_(A) and v_(B) , and pressures P_(A) and P_(B) at the points A and B , respectively. Then

An incompressible liquid flows through a horizontal tube LMN as shown in the figure. Then the velocity V of the liquid throught he tube N is:

Calculate the velocity with which the liquid gushes out of the 4cm^(2) outlet, if the liquid flowing in the tube is water and liquid in U tube has a specific gravity 12 . Velocity of liquid at point A is sqrt(20.2)m//s

Figure shows a liquid flowing through a tube at the rate of 0.1 m^(3)//s . The tube is branched into two semicircular tubes of cross-sectional area A//3 and 2A//3 . The velocity of liquid at Q is (the cross section of the main tube is A =10^(-2) m^(2) and v_(p) = 20 m//s )

A liquid of coefficient of viscosity eta is flowing steadily through a capillary tube of radius r and length I. If V is volume of liquid flowing per sec. the pressure difference P at the end of tube is given by

A fluid is flowing through a tube of length L. The radius of the tube is r and the velocity of the fluid is v. If the radius of the tube is increased to 2r, then what will be the new velocity?

A liquid of density rho and coefficient of viscosity eta , flows with velocity upsilon through a tube of diameter D. A quantity R = (rho upsilon D)/(eta) determines whether the flow will be streamlined or turbulent. R has the dimension of

Poiseuille's's law for the flow of a liquid in a capillary tube is given by eta=(piDeltaPa^(4))/(8LV) where eta = co-efficient of viscosity of a liquid DeltaP = Pressure difference across a length (L) of a tube of radius (a) and V = Volume of the liquid flowing per second The maximum error that enters the calculations of eta is due to the measurement of

In a thermally insulated tube of cross sectional area 4cm^(2) a liquid of thermal expansion coefficeint 10^(3)K^(-1) is flowing. Its velocity at the entrance is 0.1m//s . At the middle of the tube a heater of a power of 10 kW is heating the liquid. The specific heat capacity of the liquid is 1.5 kJ/(kg,K), and its density is 1500kg//m^(3) at the entrance. Q. How much bigger is the volume rate of flow at the end of the tube than at the entrance in cubic meters?
