Approved subjects are in **bold**.

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

Qualifications: Eight hours of chemistry at university level. Perfect score on WyzAnt test. Many years in the process industry working on refineries and process plants.

I have taken math courses through advanced calculus.

I have taken a college course in descriptive geometry.

I am skilled at using vector algebra to determine geometrical relationships between shapes and vectors.

I have taken a graduate level course in mechanical vibrations. Linear algebra is one means used to calculate eigenvalues and eigenvectors of vibrating masses for which the geometry, mass, stiffness, and damping characteristics are known. I have successfully applied linear algebra to a vertical, four-stage firewater pump driven by a six-cylinder Diesel engine through a right angle gear in an attempt to determine the critical speeds of the engine/pump system which had thirteen degrees of freedom. The pump shafts were breaking in torsional shear on a regular basis. Two of the natural frequencies calculated by my mathematical model matched two frequencies measured in the field on the actual apparatus.

My educational background and work history qualify me to tutor in the field of mechanical engineering. I have taken the following graduate courses in mechanical engineering: general heat transfer, convective heat transfer, fluid mechanics, mechanical vibration, and thermodynamics.

I have used these courses in my professional work, and have tutored younger engineers in several of them. I have also taken a course in advanced calculus and a course in control system theory.

My professional career involved applications of thermodynamics, fluid mechanics, and mechanical vibration to the specification and selection of large pumps and compressors and their drivers over many years. Some of these applications included compressor trains of 100 Megawatts (MW). Some of the units were modularized and weighed more than 500 metric tonnes.

I have used my courses in heat transfer, fluid mechanics, and thermodynamics in applications of fired heaters, shell-and-tube heat exchangers, air-cooled heat exchangers, refrigeration packages, and cooling towers and related equipment used in inlet air humidification systems for gas turbines.

I have also been responsible for vacuum jet ejectors, deaerators, desalters and desalination units for process plants and refineries. These items required a knowledge of mechanics of materials, metallurgy, and structural analysis which I obtained with my undergraduate degree.

I have taken three courses in fluid mechanics, one of which was at the graduate level. I have used these courses over many years in my professional career.

I have taken two courses in thermodynamics, one of which was at the graduate level. I have used these courses over many years in my professional career.

I have taken two courses in heat transfer, both at the graduate level. I have used these courses over many years in my professional career.

I have taken one course in mechanical vibrations at the graduate level. I used this course extensively in my professional career.

I have taken one course in electric circuit theory.

All of these courses can be considered as specialty areas in the field of physics.

Mathematics courses through advanced calculus and differential equations.

I have taken college math courses in algebra, trigonometry, calculus, advanced calculus, and differential equations. I am qualified by Wyzant to tutor in all math through calculus. I look forward to making a tutoring experience fun and effective.
