For h2o, determine the specified property at the indicated state. (a) t = 140°c, v = 0.5 m3/kg. find p, in bar. (b) p = 30 mpa, t = 200°c. find v, in m3/kg. (c) p = 10 mpa, t = 500°c. find v, in m3/kg. (d) t = 80°c, x = 0.2. find p, in bar, and v, in m3/kg.

What are the theoretical properties of a gas at a temperature of 0 kelvin?

The friction of the water on a boat produces an acceleration of -10. m/s2. if the boat is traveling at 30. m/s and the motor is shut off, how long it take the boat to slow down to 5.0 m/s?

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
