The purchase of the handbook now includes access to proprietary software tools. These programs allow designers to input variables like line type (suction, liquid, hot gas), energy rates, labor costs, and insulation thicknesses to automatically calculate the optimum pipe size. Unlike the nomographs of the past, these tools allow a design team to gain insight into how sizing impacts the overall cost of ownership.
