The basic energy relations for the processes as defined for perfect gases also hold for vapours all previous equations in terms of the general symbols W, Q, H, h, U, u, K, P apply to any substance under the circumstances specified. The equations derived from the assumption of an ideal gas do not hold. Remember that the areas on the [...]
In this article we will discuss about how to measure dryness fraction of steam. Barrel Calorimeter: To get the approximately dryness fraction of steam, a very simple ape called Barrel Calorimeter is used. This consists of a wooden barrel containing cold water. Steam is taken from the pipe through which it is flowing and is condensed in the cold water. [...]
