How do we calculate the efficiency of the reversible engine?

A to B is isothermal process(dT=0) so temperature is same.. B to C is isobaric process for dQ=nCpdT and C to A is isochroic process so dQ=nCvdT(dW=0)...

hope all steps are clear to you.. for any doubt please ask..

Im not getting that how the ratio W/Q can be found?

in these type of question arrows should be given.

is it clear dear ?

dear bcoz it's reversible process and chnz in internal energy is o so work done will equal to heat absorbed. so efficiency of ideal reversible heat engine is one.

like this. see the attached you will get it.

for any process we have to calculate work done in any process. in your diagram we can calculate work done from area under the curve. that area will give us work done hence we will ...

you can calculate the work done by area under the curve (area of triangle is 1/2* base * height.) and the heat intake can be calculated in isobaric and isochoric process. devide th...

carnot engine is reversible heat engine. we can calculate its efficiency . see the attached
