spreadsheet can be readily found in
the literature. Sheet 3 is included for
finding the friction losses in the pumping
system. Inside Sheet 3 are useful
tables for summing the typical resistance
coefficients for the valve, fitting,
contractions and enlargements, and
so on, and determining the relative
roughness of the piping.
To perform the viscosity correction,
input TDH, flowrate and viscosity
(in centistokes) into Sheet 4.
Then, input the correction factors
from the viscosity correction chart
into the appropriate cell in Sheet
4. This Excel spreadsheet uniquely
draws the lines on the diagram automatically
based in the user's input.
In Sheet 5, power consumption can
be found and will provide the annual
utility cost of the pump under
consideration, as a function of both
the yearly operating hours and local
electricity cost.

Joseph " Joey " Sarver is currently
pursuing a M.S. degree in
chemical engineering at the Virginia
Polytechnic Institute and State
University (VIrginia Tech; Blacksburg,
Va.). Previously, he was a
post-bachelor research assistant at
Oak Ridge National Laboratory
(ORNL) through the Oak Ridge Institute
for Science and Education
developing fabrication methods for organic spintronics
using conjugated polymeric materials. He also worked as
a co-op student for the United States Gypsum Corp. as a
project engineer in the paper division. As an undergraduate,
Sarver was actively involved in research at the Virginia
Tech Supercritical Fluids laboratories under Erdogan
Kiran. His research awards include recognition at the
2016 AIChE international conference for gradient foaming
of polymers in supercritical carbon dioxide.
Blake P. Finkenauer is a firstyear
Ph.D. candidate in chemical
engineering at Purdue University
who holds a B.S.Ch.E. degree from
Virginia Polytechnic Institute and
State University (Phone: 757-6962462;
Email: bfinkena@purdue.
edu or bfink757@vt.edu). He has
worked as a co-op at the DuPont
Spruance Plant in Nomex Process
Control and in Polyaramid Research and Development.
He also worked at NASA Langley Research Center as an
intern in the Langley Aerospace Research Student
Scholar (LARSS) Program. As a student at Virginia Tech,
Finkenauer conducted undergraduate research in processing
thermotropic liquid crystalline polymers under
Donald Baird. For his senior design project, he worked
with a team of three students for BAE Systems. Finkenauer
received numerous awards for his academic
achievements, including the AIChE Donald F. Othmer
Sophomore Academic Excellence Award, ACS James
Lewis Howe Award, and a Ross Fellowship.
Y. A. Liu is an Alumni Distinguished
Professor and the Frank
C. Vilbrandt Endowed Professor of
Chemical Engineering at Virginia
Polytechnic Institute and State
University (Virginia Tech; Blacksburg,
VA 24061; Phone: 540231-7800;
Email:
design@vt.
edu). Over the past 30 years, Liu
has taught hands-on training
courses on energy and water savings, computer-aided
design and advanced process control to over 7,000
practicing engineers in the U.S., China and Taiwan. He
served as a senior advisor to Sinopec from 2001 to
2015, and to PetroChina since 2016. He has taught
design courses to graduating seniors in chemical engineering
since 1982, for which pump sizing and selection
is a course topic. He is a recipient of the George
Westinghouse Award and Fred Merryfield Design Award
from the American Society for Engineering Education,
the Outstanding Faculty Award from the Virginia's governor,
and the National Friendship Award from the China's
premier. In 2015, he received Virginia Professor of
the Year award from the highly selective U.S. Professors
of the Year program, sponsored by the Carnegie Foundation
for the Advancement of Teaching and the Council
for Advancement and Support of Education.
