Steam Quality Questions

1. 20 m³ of Steam at 1 atm and 373.15K contains 1litre of water. What is the quality of the steam?

1. 5 m³ of steam at 9.319 bar pressure and 450K contains 30litre of water what is the quality of the steam

1. The steam quality at 1atm is 67% what is the specific volume of the mixture

 

Steam table questions

 

Direct extraction of data from tables

1) Critical point properties of water

2) Latent heat of vaporisation of water at 2.5 bar

3) Specific heat capacity of water at 45 c

4)enthalpy of ammonia at 20 c at 50 degrees c of superheat

 

 

Interpolation

5) Calculate the saturated vapour pressure at 97.5 °C

6) Calculate the enthalpy of vaporisation 159.8 F

7) Calculate the internal energy of the saturated liquid at 1842Psi

 

 

Double interpolation

8) Calculate the molar volume of superheated steam at 0.67MPa and 593.15 K

9) Calculate the enthalpy superheated steam at 9750mmhg and 465 °C

10) Calculate the internal energy of superheated steam at 58.5 bar and 1499.67 ^oR

11) Calculate the enthalpy of ammonia at 41°C and 7.2bar pressure

 

Use of water property table on page 11

 

12) The steam quality at 150°C is 45% what is the specific volume of the mixture.(will need to interpolate data)

 

Use of compressed water table on page 12

13) Enthalpy of compressed water at 229 °C and 300 bar pressure

Moderator Note

haley5p,

 

Please note that this is obviously homework. You will not get any answers, unless you show what you have so far done to solve these problems. Posting only the questions is not sufficient. You are obviously doing some engineering course, not a management course, so asking other people to do your work is not going to teach you the necessary skills to pass the class.

 

Everybody,

Please do not answer any questions until our OP has shown any efforts into solving these problems.
