The pressure on an object of bulk modulus B undergoing hydraulic compression due to a stress exerted by surrounding fluid having volume strain `((DeltaV)/(V))`

A

`B^(2)((DeltaV)/(V))`

B

`B((DeltaV)/(V))^(2)`

C

`(1)/(B)((DeltaV)/(V))`

D

`B((DeltaV)/(V))`

Text Solution

Verified by Experts

The correct Answer is:
D

(d) `B=("Normal stress")/("Volume strain")=|(p)/(-((DeltaV)/(V)))|=|-(pV)/(V)|`
`p=V(DeltaV)/(V)=B((DeltaV)/(V))`
where, normal stress =p, volume strain `=-(DeltaV)/(V)`

A gaseous sample is generally allowed to do only expansion // compression type work against its surroundings The work done in case of an irreversible expansion ( in the intermediate stages of expansion // compression the states of gases are not defined). The work done can be calculated using dw= -P_(ext)dV while in case of reversible process the work done can be calculated using dw= -PdV where P is pressure of gas at some intermediate stages. Like for an isothermal reversible process. Since P=(nRT)/(V) , so w=intdW= - underset(v_(i))overset(v_(f))int(nRT)/(V).dV= -nRT ln(V_(f)/(V_(i))) Since dw= PdV so magnitude of work done can also be calculated by calculating the area under the PV curve of the reversible process in PV diagram. If four identical samples of an ideal gas initially at similar state (P_(0),V_(0),T_(0)) are allowed to expand to double their volumes by four different process. I: by isothermal irreversible process II: by reversible process having equation P^(2)V= constant III. by reversible adiabatic process IV. by irreversible adiabatic expansion against constant external pressure. Then, in the graph shown in the final state is represented by four different points then, the correct match can be
