    Undergrad Why is the work done by an ideal gas the area under a PV diagram?

    just remember that this is true under the assumption of quasistatic conditions, which is almost static but notquite. think about a situation where the internal pressure is much higher than the external presssure. how do you calculate work then? thafeera

    Undergrad Why water turbine have higher efficiency then steam turbine?

    the betz limit? isn't it for wind turbines? it is does not match steam turbines at all!

    Undergrad Why water turbine have higher efficiency then steam turbine?

    thr comaprison isn't fair, a steam turbine is just one component of the steam engine. by definition, the overall thermal efficiency acounts for all the components of the steam engine. the steam turbine is just one component. thafeera
