Textbook Question
Chapter 4, Problem 4.16P
A fuel distributor supplies four liquid fuels, each of which has a different ratio of ethanol to gasoline.
Five percent of the demand is for E100 (pure ethanol), 15% for E85 (85.0 volume% ethanol), 40% for E10 (10.0% ethanol), and the remainder for pure gasoline. The distributor blends gasoline and ethanol to produce E85 and E10, and the four products are produced continuously.
- Draw and label a flowchart for the blending operation, letting V represent the combined volumetric flow rate of all four fuels and VGand VE represent the volumetric flow rates of gasoline and ethanol sold as fuels and sent to the blending operation.

Ex. HW. A vertical glass tube, 2cm ID & 5m long in heated
uniformly over its length. The water enter at (200-204 C) &
68.9 bar calculated the pressure drop if the flowrate 0.15
Kg/s & the power applied as a heat to the fluid is 100KW
using the homogeneous model. Given that enthalpy at inlet
temp.=0.87MJ/Kg, enthalpy saturation temp (285C)=1.26
MJ/Kg and μl=0.972*10-4 Ns/m2, μG=2.89*10-5 Ns/m2,
UG=2.515*10-2m3/Kg and the change in UG over range of
pressure=-4.45*10-4m3/Kg/bar.
4. An experimental test rig is used to examine two-phase flow regimes
in horizontal pipelines. A particular experiment involved uses air
and water at a temperature of 25°C, which flow through a horizontal
glass tube with an internal diameter of 25.4 mm and a length of 40 m.
Water is admitted at a controlled rate of 0.026 kgs at one end and air
at a rate of 5 x 104 kgs in the same direction. The density of water
is 1000 kgm³, and the density of air is 1.2 kgm. Determine the mass
flow rate, the mean density, gas void fraction, and the superficial
velocities of the air and water. Answer: 0.02605 kgs 1, 61.1 kgm³, 0.94,
0.822 ms-1, 0.051 ms-1
