In the derivation of `P_1-P_2=rhogz` it was asumed that the liquid is incompressible. Why will this equation not be stictly valid for a compressible liquid?

A : Equation ofcontinuity is A_(1) v_(1) rho_(1) = A_(2) v_(2) rho_(2) (symbols have their usual meanings). R : Equation of continuity is valid only for incompressible liquids.

Give reason to explain why: Gases are so easily compressible whereas it is impossible to compress a solid or a liquid.

A homogeneous solid cylinder of length L(LltH/2), cross-sectional area A/5 is immersed such that it floats with its axis vertical at the liquid-liquid interface with length L/4 in the denser liquid as shown in the figure. The lower density liquid is open to atmosphere having pressure P_0 . Then density D of solid is given by

In the reaction of p-chlorotoluene with KNH_(2) is liquid NH_(3) the major product is .

A liquid of volume of 100 L and at the external pressure of 10 atm-Lt the liquid is confined inside an adiabatic bath. External pressure of the liquid is suddenly increased to 100 atm and the liquid gets compressed by 1 L against this pressure then find, (i) Work (ii) Delta U (iii) Delta H

STATEMENT - 1 Bernoulli's theorem is conversation of energy because STATEMENT - 2 Mass flowing per second at every cross section in tube of flow corresponding to incompressible liquid remains constant.

A wooden cylinder of length l floats vertically in a liquid of specific gravity rho with ((1)/(3))^(rd) part of its length submerged. Another liquid that is immiscible with the previous liquid is poured into it, to just completely submerge the cylinder. If the density of the liquid at the bottom, density of cylinder and density of upper liquid are in G.P., find the fraction of the cylinder submerged in lower liquid.

Assertion : Bulk modulus of an incompressible liquid is infinite. Reason : Compressibility is inverse of bulk modulus.

when an ideal gas with pressure p and volume V is compressed Isothermally to one - fourth of its volume, is pressure is P_1 when the same gas is compressed polytropically according to the equation PV^(1.5) contents to one - fourth of its initial volume, the pressure is P_2 the ratio P_1/P_2 is

A container of large uniform cross-sectional area A resting on a horizontal surface, holes two immiscible, non-viscous and incompressible liquids of densities d and 2d each of height H//2 as shown in the figure. The lower density liquid is open to the atmosphere having pressure P_(0) . A homogeneous solid cylinder of length L(LltH//2) and cross-sectional area A//5 is immersed such that it floats with its axis vertical at the liquid-liquid interface with length L//4 in the denser liquid, The density D of the material of the floating cylinder is
