Teaching Assistants
ENGI 2102聽聽 Thermo-Fluid Engineering I

TA 90 hours @ $24.41/hr

To Apply: email your cover letter and resume to engineering@dal.ca with the Subject line 鈥� 鈥淎pplication for TA Position 鈥� ENGI 2102 Fall 2019鈥� by Sept 4, 2019

Course Description

This course introduces the engineering sciences of thermodynamics and fluid mechanics in an integrated manner. A unified approach to energy transfer in thermal and mechanical systems is presented. The course covers basic properties of fluids, fluid statics, simplified analyses of fluid motion, the basic laws of thermodynamics, and the application of control volume techniques to engineering problems. Power systems are introduced through a study of the Rankine cycle.

Types of Duties

The principle roles of the Teaching Assistant (TA) for ENGI 2102 are as follows:

Laboratory Assistance: to provide supervision and guidance for 4 laboratory experiments; to maintain a safe and professional laboratory while assisting students; to assist students in troubleshooting equipment and/or technical issues; to ensure a safe and professional laboratory before and after the laboratory by assisting with equipment mounting and demounting; assisting students with Brightspace Labs.

Tutorial Assistance: to provide assistance and/or lead tutorial sessions; to understand and facilitate the understanding of the Course Learning Outcomes; assisting students with Brightspace Assignments.

Invigilation of Exams: all TAs must be available for at least one of the midterm and or final exam times for invigilation.

PEAS Training: new TAs and returning TAs must participate in Process Engineering and Applied Sciences (PEAS) ENGI 2102 laboratory training program and safety orientation.

Requirements

An understanding of the following:

Apply the pressure-depth relation and the concept of buoyancy to analyze systems involving fluids at rest.
Define and differentiate between internal energy, kinetic energy, potential energy, heat and work.
Estimate the thermodynamic properties of fluids using tabulated data, charts and correlations, and use this data to solve thermodynamic and fluid mechanics problems.
Break down a thermodynamic cycle or process into appropriate subsystems or subprocesses for the application of the first and second laws of thermodynamics.
Apply the first law of thermodynamics to analyze closed systems, steady-flow devices, and power and refrigeration cycles.
Apply the second law of thermodynamics to analyze closed systems, steady-flow devices, and power and refrigeration cycles.
Apply the mechanical energy balance and Bernoulli鈥檚 equation to fluid flow problems.
Apply Newton鈥檚 law of viscosity to calculate fluid friction forces for one-dimensional flow of Newtonian fluids.
Calculate surface tension forces acting on gas-liquid and gas-liquid-solid interfaces.
Calculate friction losses for fluids flowing through pipes and fittings.
Acquire and interpret experimental data by performing experiments in fluid statics, fluid dynamics, and thermodynamics.
