4. Consider the two separate sets of measured data for a silt-loam soil measured by Mualem
(1976): (1) suction versus water content, and (2) suction versus relative permeability of
unsaturated soil, k/ks. Assume that 0s 0.396, 0res = 0.131, and Ks=5.74×10-7 m/s.
a. Using the method of least squares in Excel, compute the best-fit values for αNG (kPa¹)
and nvg for the van Genuchten (1980) relationship for data set # 1 (assume m = 1-1/nvG).
See the example spreadsheet in the homework folder under the files section of Canvas for
help in performing this calculation.
b. Repeat part (a) and estimate the λ and ac parameters for the Brooks and Corey (1964)
SWRC for data set #1. Note that you may need to include an "if" statement at the air
entry suction.
c. Plot the data for the SWRC versus the fitted van Genuchten (1980) and Brooks and
Corey (1964) curves. Which relationship matches the capillary pressure data better (BC
or VG)? Explain…

- 1. (20 points) Steam (6000 kg/h, 10 bar, 400°C) is passed through an adiabatic turbine that drives a shaft to generate power. The steam leaving the turbine is at 0.5 bar and passes to a chiller where heat is removed at the rate of 1.25 x 107 kJ/h. Saturated liquid leaves the chiller at 0.5 bar. (a) How much work (kW) is produced in the turbine? (b) What is the quality of steam leaving the turbine? Sometimes, steam produced is 'wet' in nature, and is composed of saturated water vapor and entrained water droplets. In such cases, quality is defined as the fraction of steam that is vapor.arrow_forwardWLV2 | Online teaching and × + w.com/ilrn/takeAssignment/takeCovalentActivity.do?locator-assignment-take A १ eq eq eq [Review Topics] [Referen Draw the structure of 3,3-dimethylbutanal in the window below. • In cases where there is more than one answer, just draw one. 985 + / $ Sn [ ] ChemDoodle ? req Submit Answer Retry Entire Group 8 more group attempts remaining req req Cengage Learning Cengage Technical Supportarrow_forwardA flat-sheet membrane of thickness, L, and surface area, S, separates two fluids (see figure).

- Develop a purification train for a facility where first process is a perfusion upstream bioreactors 500L producing low cell culture titer of approx. 0.5 g/L perfusing at 2 VVD over 30 days. The current facility has a secondary clarification process for the perfusate coming from the bioreactor. Secondary depth filtration clarification capacity of 200 L/m2. Identify the correct filter area, and system (pump) requirements for the process scale. Also identify optimal flowrates for flushing and processing, total process time, buffer volumes required. Assume 10 L/m2 holdup of the depth filters identify the size of the tank required to collect the filtrate. Average yield of overall clarification is 80% estimate the titer in the clarified pool.arrow_forwardBioprocessing/ Protein isolation and purification.
