Homwork-6.png Homework-6 P.1 Calculate the dryness fraction (quality) of steam which has 1.5 Kg of water in suspension with 50 Kg of steam? A vessel having a volume of 0.05 m contains a mixture of saturated water and saturated steam at a temperature of 245 ° C. The mass of liquid present is 10 Kg. P.2 Find the following: (a) The pressure. (b) The mass. (c) The specific volume. (d) The specific enthalpy (e) The specific entropy. (f) The specific internal energy.
Pls solve accurate and fast A 1-kg steam-water mixture at 1.0 MPa is contained in an inflexible tank. Heat is added until the pressure rises to 3.5 MPa and the temperature to 400: Determine the heat added
b) The high pressure units on a steam plant operate at 10bar (gauge), and the condensate is sub-cooled by 9.5K. If the mass flow rate of condensate is 10 kg/s, use the provided steam tables to determine how much saturated steam at 1.5 bar this condensate could produce. Note it is sufficiently accurate for high pressure condensate, as in this question, to assume that the specific enthalpy is the same as for the saturated liquid at the same temperature.
