A 1-shell-pass and 8-tube-passes heat exchanger is used to heat glycerin (c p = 0.60 Btu/lbm
Question:
A 1-shell-pass and 8-tube-passes heat exchanger is used to heat glycerin (cp = 0.60 Btu/lbm · °F) from 65°F to 140°F by hot water (cp = 1.0 Btu/lbm · °F) that enters the thin walled 0.5-in-diameter tubes at 175°F and leaves at 120°F. The total length of the tubes in the heat exchanger is 500 ft. The convection heat transfer coefficient is 4 Btu/h · ft2 · °F on the glycerin (shell) side and 50 Btu/h · ft2 · °F on the water (tube) side. Determine the rate of heat transfer in the heat exchanger
(a) Before any fouling occurs
(b) After fouling with a fouling factor of 0.002 h · ft2 · °F/Btu on the outer surfaces of the tubes.

I am a retired teacher with 6 years of experience teaching various science subjects to high school students and undergraduate students. This background enables me to be able to help tutor students who are struggling with the science of business component of their education. Teaching difficult subjects has definitely taught me patience. There is no greater joy for me than to patiently guide a student to the correct answer. When a student has that "aha!" moment, all my efforts are worth it.
The Common Core standards are a useful yardstick for measuring how well students are doing. My students consistently met or exceeded the Common Core standards for science. I believe in working with each student's individual learning styles to help them understand the material. If students were struggling with a concept, I would figure out a different way to teach or apply that concept. I was voted Teacher of the Year six times in my career. I also won an award for Innovative Teaching Style at the 2011 National Teaching Conference.
