Computer usage: The student will generate programs using a PC to solve applications of fluid mechanics.

Laboratory projects: The fluid/thermal lab, MCT-334L, and the Fluid Power Lab, MCT-336L, will use concepts developed in this course.

Oral and written communication requirements: Students will prepare written reports associated with the computer project.

Calculus usage: Integral calculus is required to relate fluid velocity across a flow area to a flow rate. These concepts of calculus are used qualitatively to understand flow rate.

Library usage: Limited
