# CBEMS 125B Heat Transfer (2012-2013)

#### CBEMS 125B Heat Transfer

**CBEMS 125B Heat Transfer (Credit Units: 3)** Principles of conduction, radiation, and convection of heat; phenomenological rate laws, differential and macroscropic energy balances; heat transfer rates, steady state and unsteady stats conduction, convection; applications to chemical and related industries. Prerequisite: CBEMS125A with a grade of C- or better. Chemical Engineering and Materials Science Engineering majors have first consideration for enrollment. Only one course from CBEMS 125B, ENGRMAE 120 may be taken for credit. (Design units: 1)
