Steam is raised as saturated steam at 6 bar (g) and supplied to the first ( high pressure ) piston. The steam then exhausts from piston 1 at 3 bar (g).
The steam is thought to expand adiabatically in accordance with
PV^( 135 .1)= Constant
Given the initial volume is...
can u please provide me a web page to look at the specific volume of saturated liquid water at 9 MPa? or a good steam tables web page to look at it?
I have books with steam tables, steam tables in pdf and really DOES NOT APPEAR LIQUID WATER.
WHAT APPEARS ITS COMPRESSED WATER.?IS THAT IT?
First, I convert the pressure given to bar.
so: 9 atmx (1.01325bar)/1atm = 91.1925 bar
I look these temperature in the steam table for specific volume of saturated steam and saturated liquid water, and these temperature does not appear.
so I need to interpolate.How can I do it?
The problem doesn´t mention if dry stream and liquid water are present together.
The problem only provides me rate of pipe 100kg/s. The quality x=80 % =0.80
and the pressure= 90 atm. Determine the volumetric flows of dry steam and liquid water.
do u know any formula to find the volumetric...
It doesn´t say. I think it will be gauge pressure
units of steam tables? vg= metres cube/kg
If u want to have a look, Steam tables attached
By the way, I always do everything different from everybody else, that why I´m different
No. I don´t know how to find the temperature of both. Looking at the pressure 90 atm for the liquid water and vapor, I will find the temperature of both.Then I will determine the specific volume of both?
Yes, exactly, I´m using the steam tables.
Given T=572 ºF, pressure= 145 psi (g) using the steam tables and ideal gas law
Molar Mass= 18 g/mol for water
Find: Is the water vapour acting ideally?
Ideal Gas Law: PV=nRT
P is the pressure =145 psi (g)
V is the molar volume
R= Ideal gas constant...
