Chapter 6, Problem 6.31P
A laminar flow element (LFE) (Meriam Instrument Co.) measures low gas-flow rates with a bundle of capillary tubes or ducts packed inside a large outer tube. Consider oxygen at 20°C and 1 atm flowing at 84 ft3/min in a 4-in-diameter pipe. (a) Is the flow turbulent when approaching the element? (b) If there are 1000 capillary tubes, L = 4 in, select a tube diameter to keep Red below 1500 and also to keep the tube pressure drop no greater than 0.5 lbf/in2. (c) Do the tubes selected in part (b) fit nicely within the approach pipe?

As a process engineer, you are designing a new drinking water treatment plant
using conventional treatment process including Two Rapid Mixers as follows:
The design flow is 50 million gallons per day (MGD) (1 Gallon = 3.785 L, 1
m³ = 1000 L).
The average temperature of water is 5°C with a dynamic
viscosity,
μ = 1.519 x 10-3
Pa.Sec
In each rapid mixer with a square shape, detention time, e = 1 min, water
depth H = 13 ft, and power input P = 1.5 kw (1 ft = 0.3048 m, 1 KW = 1,000 W)
The equivalent diameter, TE for each rapid mixer is

What is the size (thickness) of u and 8 for turbulent flow in a 4 in (100
mm) nominal pipe? Hueristics suggest that typical pressure drop for
pipelines is 2 psi/100 ft or 0.45 kPa/m. Use the viscosity of water at 20
C for physical properties.
Example: Darcy's Head Loss Equation
A pipe 100 feet long and 20 inches in diameter contains water at 200°F flowing at a
mass flow rate of 700 lbm/sec. The water has a density of 60 lbm/ft³ and a viscosity of
1.978x107 Ibf-sec/ft?. The relative roughness of the pipe is 0.00008. Calculate the
head loss for the pipe.
