Natural gas having a specific gravity relative to air of 0.60 and a viscosity of 0.011 cP is flowing through a 6-in. Schedule 40 pipe in which is installed a standard sharp-edged orifice equipped with flange taps. The gas is at 100°F and 20lb/in? abs at the upstream tap. The manometer reading is 46.3 in. of water at 60°F. The ratio of specific heats for natural gas is 1.30. The diameter of the orifice is 2.00 in. Calculate the rate of flow of gas through the line in cubic feet.

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…

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_forward
