Question
Chapter 8, Problem 8.9P
(a)
Interpretation Introduction
Interpretation:
The pressure drop at maximum flow is to be determined.
Concept Introduction:
Pressure drop in orifice meter is directly proportional to the square of velocity of flow. Other factors such as dimensionless diameter ratio depend on the shape of orifice. Lastly, some of the dimensional features of the pipe are universal and hence provide the best assumptions.
(b)
Interpretation Introduction
Interpretation:
The effect of flow condition on the accuracy of flow measurement is to be determined.
Concept Introduction:
Pressure drop in orifice meter is directly proportional to the square of flow velocity.

8.3 Fractionation of a Protein Solution
Four proteins are dissolved in solution. The
constants in the Cohn equation (see Example 8.1) for the proteins are given in
Table P8.3 along with the concentration of each protein in solution. Assume that
the Cohn equation constants are valid when other proteins are present.
(a) Determine the maximum percentage recovery of protein 4 that can be obtained if
it is desired to obtain a precipitate containing 100% protein 4.
(b) Determine the maximum percentage recovery of protein 3 that can be obtained if
it is desired to obtain a mother liquor containing 99% protein 3.

- Liquid ammonia (NH₃) is applied as a fertilizer. You are working for a company that applies the ammonia (they charge a lot for every pound they apply to the soil) and you keep track of the pounds of ammonia that has been applied from the tank on the back end of your pickup (four-wheel drive with big tires). After the liquid has been emptied from the tank, there is still gas ammonia left in the tank. It has been sitting in the sun and its temperature is 125°F. Also, the pressure gauge at the top of the tank shows 230 psig (pounds per square inch gauge). The tank has a volume of 120 ft³.

- chemical engineering The answer for the specific molar volume of nitrogen gas is 12.089x10^(-5) m^3/mol. How was this answer determined? You need to use the ideal gas law to determine the specific molar volume.

The Henry's law constant for nitrogen in water is recommended by NIST to be well represented by KH = 0.000625 exp[1300 (1/T - 1/298.15)] mol N2/(kg H2O bar), where T is measured in Kelvin.
