The density of a compressible fluid changes with pressure, while the density of an incompressible fluid is not affected by pressure (assuming isothermal conditions).
No, for gases if the difference in pressure results in a density change of less than approximately thirty percent (30%), the fluid may be treated as incompressible by assuming the density to be the average density which remains constant.

I think a vessel is containing a fluid under high pressure whereas a drum contain a fluid with no or low pressure.
Hot Approach: It is difference in temperature of hot fluid inlet temperature and cold fluid outlet temperature Cold Approach: It is difference in temperature of Hot fluid outlet temperature and cold fluid inlet temperature. Mohsin
The use of the LMTD arises straightforwardly from the analysis of a heat exchanger with constant flow rate and fluid thermal properties. It is a simple method to approximated the temperature diving force in a heat exchanger. The LMTD is a logarithmic average of the temperature difference between the hot and cold streams at each end of the exchanger. The larger the LMTD, the more heat is transferred.
An obstruction (orifice) is placed in a pipe filled with fluid. The pressure of the fluid is measured at two different points: 1) just upstream of the orifice and, 2) close to the contraction of the fluid (vena contracta). The difference in these two pressures is known as differential pressure. The differential pressure across an obstruction (orifice) in a pipe of fluid is proportional to the square of the velocity of the fluid. Many factors associated with the pipe, orifice and fluid affect the measurement. Satisfactory measurement requires steady-state, homogeneous, turbulent flowing fluids. Other properties which affect the measurement include: the ratio of pipe diameter to orifice diameter and the density, temperature, compressibility and viscosity of the fluid.
if the density of the fluid changes with respect to pressure is called compressible fluid f the density of the fluid does not changes with respect to pressure is called incompressible fluid
It can't be made compressible, if that's what you mean - unless you turn it into steam.There really is no such thing as an incompressible fluid; but the amount a liquid's volume changes under pressure is so little, that for many practical purposes it can be considered incompressible.
compressible fluid changes its volume when external pressure is applied and in-compressible fluid does not change its volume due to external pressure
No, if the pressure difference results in a density change of less than thirty percent (30%) the fluid may be treated as incompressible by assuming the density of the fluid equals the average density and that the density is constant.

Which word do you not understand? incompressible - cannot be compressed viscous - resistant to flow, "thick" fluid - substance that flows (both gases and liquids are fluids, but gases are usually compressible; liquids generally aren't)

Yes, air is a compressible fluid. Water is not a compressible fluid.
Nothing is inincompressible For practical propose, it defined water as incompressible since its' compressibility is very low. To compressed water down to 99/100 of original volume you would need a pressure of 217 Bar approximately. Any normal pressure vessel would burst at such pressure. It is then considered water as incompressible.
Can be compressed but not a fluid
Fluids include liquids and gasses. Liquids are not compressible. Gasses are compressible. Water is a liquid and it not compressible.
Ideal Fluid:An incompressible fluid that has no internal viscosity.
In incompressible fluid density is same because velocity gradient is same on every layer of liquid at any cross section.
