Question

A
Cylinder
Contains 1kg of
Certain
fluid
inside pressure of 20 bar. The
fluid is allows to extend reversinly behind
biston according
to a
low pv²= Constant
untill the volume is doubled the fluid
is turn
reversively at constant
pressure
untill the piston regains its original
position heat is supplied reversively with
true
piston firmly
enclosed in piston
untill the pressure
rises to
the
orignal volume
of 20 bar Calculate
the net
work to done
by the fluid for an initial
volume of 0.05m3​

Answer 1

Explanation:

Answer :

A::C::D

Solution :

(a) Heat supplied to the cylinder =Energy used to raise <br> the temperature of cylinder+Energy used for work <br> done by the cylinder. <br> Energy used to raise the temperature =

<br>

<br> where

is the final temperature of the cylider. <br> Energy used for work done <br>

<br> The final volume

<br>

<br> From (ii) and (iii), <br>

<br>

<br>

<br>

Heat supplied to the cylinder <br>

<br>

<br>

<br> (b)

<br> (c)
