A steam press at 650Kpa + dryness fraction of 0.9% flows along a pipe at a rate of 3.5Kg per second. Steam mixes with additional steam that has been throttled from a pressure of 2000Kpa to a pressure of 800Kpa which enters from a branch pipe. If the resulting mixture is dry at 800Kpa find the amount of additional steam entering from the branch pipe?© BrainMass Inc. brainmass.com October 16, 2018, 3:51 pm ad1c9bdddf
90% of 3.5 Kg = 3.15 Kg dry steam and rest 10% i.e. 0.35 Kg is liquid.
If you look at the steam table, if the pressure is ...
This solution responds in 75 words to the relationship between pressure and enthalpy and how this relationship can be used with calculations to find the additional steam entering the branch pipe.
Vapor Pressure of Mixtures of Miscible vs. Immiscible Liquids
Consider a physical explanation for the difference of vapour pressure of miscible and immiscible solutions. For immiscible the total vapour pressure is equal to the sum of the pressure from the pure liquids but and miscible liquids pressure vapour pressure follows raoults law. What is the physical justification for this?View Full Posting Details
