Author of several well-received Process Engineering Guides in Heat Transfer, Peter Hills brings more than 25 years of experience in a variety of thermal applications. The book provides a practical insight into the design, operations, specification, and purchasing of heat transfer equipment. The engineer is led through logical understanding of all processes involved and taught to distinguish the practical applications from the computer codes. Covers a wide and detailed variety of process and power equipment.
