Question

carry a reasonable amount of water quickly and without too much friction loss. What happens to the friction loss and the required pump power when you try to move water through the same pipeline at a velocity of 15 ft/s? Real Gas Volumes The Soave - Redlich - Kwong (SRK) equation of state is a commonly used equation that relates the temperature, pressure, and volume of a gas under conditions when the behavior of the gas cannot be considered ideal (e.g., moderate temperature and high pressure). The equation is P = where alpha, a, and b are parameters specific to the gas, R is the ideal gas constant, P is the absolute pressure, T is absolute temperature, and is the molar volume (volume per mole of gas). For common gases, the parameters alpha, a, and b can be readily determined from available data. Then, if you know the molar volume of the gas, the SRK equation is easy to solve for either pressure or temperature. However, if you know the temperature and pressure and need to find the molar volume, an iterative solution is required. Determine the molar volume of ammonia at 300 degree C and 1200 kPa by using the ideal gas equation. using the SRK equation and an iterative solve block. For ammonia at these conditions, alpha = 0.7007 a = 430.9 kPa middot L2/mole2 b = 0.0259 L/mole.

Explanation / Answer

V=RT/P as calculating molar n=1

=8.314*573/1200*103=3.97*10-3 m3=3.97Ltr

V^=V/1=V

Thus, P= R/(V-b) -?a/V(V+b)

Putting values as provided

1200=8.314/(V-0.0259) - 0.7007*430.9/V(V+0.0259)

1200=[8.314*(V2+0.0259V)-0.7007*430.9(V-0.0259)]/[V(V+0.0259)(V-0.0259)]

1200V(V2-6.7081*10-4)=8.314V2+0.21533V+301.93V-7.82

1200V3-8.314V2- 302.95V+7.82=0

V=0.496 ltr
