1. To measure the liquid permeability of a sample, a core 2 cm in diameter and 5 cm
long was used. Brine was flowed through the sample at a flow rate of 1 cm3/sec. If
the pressure drop was measured to be 5 x 107 dynes

Chapter 9 Compressible Flow
9.1 An ideal gas flows adiabatically through a duct. At section 1, p1 140 kPa, T1
260C, and V1 75 m/s. Farther downstream, p2 30 kPa and T2 207C. Calculate V2
in m/s and s2 s1 in J/(kgK) if the gas is (a) air, k 1.4, and (b) a

Chapter 6 Viscous Flow in Ducts
P6.1
An engineer claims that flow of SAE 30W oil, at 20C, through a 5-cm-diameter smooth
pipe at 1 million N/h, is laminar. Do you agree? A million newtons is a lot, so this sounds like
an awfully high flow rate.
Solution:

Chapter 7 Flow Past Immersed Bodies
P7.1
An ideal gas, at 20C and 1 atm, flows at 12 m/s past a thin flat plate. At a
position 60 cm downstream of the leading edge, the boundary layer thickness is 5 mm.
Which of the 13 gases in Table A.4 is this likely to

inter-bedded sands and shaly-sands. The capillary pressure curves (measured
with crude oil and brine) for the sands and the shaly-sands are gi

1. Calculate the capillary pressure curve (VS wetting fluid saturation) for a capillary
micromodel composed 5 channels in parallel (similar to micromodel of three
channels shown in class slide 17 [L05.A] from left to right).

Effective porosity vs. Absolute porosity
Most oil & gas companies want the total porosity (because it makes their reserves look good)
Shale porosity ~ 5 % since its tight and estimations are not always accurate
