Consider a glass of ice water at 0 °C. Moisture from the air is observed to condense on the outer sides of the glass. This condensation causes the ice in the glass to melt faster than if there were no condensation. For this problem use LvLv= 2430 kJ/kg for the latent heat of vaporization of water at 37 °C as a better approximation than LvLv for water at 100 °C.) Determine the mass of ice, in grams, in the glass that would melt as a result of the condensation of 6.6 g of water from the air onto the sides of the glass.
Find the dryness fraction of a steam having a specific volume of 15 m3 /kg after expansion in a turbine. The specific volumes of saturated liquid and saturated vapor corresponding to the pressure are 0.001 m3 /kg and 15.25 m3 /kg, respectively.
What is the difference between specific internal energy and specific enthalpy in first law of Thermodyanamics and when should i use which? From what i understand so far for constant pressure process, we use q-w=h2-h1 and constant volume process, we use q-w = u2-u1. But this isnt the answer i am looking for.
