Using this godawful textbook (Fundamental of Thermal-Fluid Sciences, Cengel) for Thermodynamics. It's thick as three bibles, has lots of pretty pictures, constantly goes off on tangents, avoids 'advanced' stuff like calculus like the plague and is filled to the brim with problems involving converting fahrenheits to celsius, looking stuff up in tables and various unnecessary numerical computations. In other words, it's a typical engineering textbook. Can anyone direct me to an introductory level book, or even better a pdf, without a bunch of fluff, preferrably one with interesting, compact problems? Not looking for grad-level treatment, just something more to-the-point.
