ocean energy and tidal power depend on suitable sites, and the number of
suitatable sites is relatively few, yet engineers continue to try to develop
machinery that can be used in normal ocean waters to generate electric
power. Calculation procedures given in this section show how to utilize
suitable ocean sites to generate electric power reliably and economically. The
search for more ways to harness the waves and tidal changes to generate
power will continue for as long as civilization needs electricity.
Heat transfer and energy conservation calculation procedures are presented
in Section 11 of this handbook. Since energy can be used and reused with
proper heat transfer, as well as conserved, the calculation procedures in this
section are very important to energy engineers worldwide. Energy
conservation by reducing heat losses and conserving available heat are
important topics covered in this section of the handbook.
Section 12 deals with the important topic of fluid transfer engineering.
Thus, piping, pumps (of many different types), fluid viscosity, energy
conservation in choice of pump, materials selection for pump parts, and
economic competitive analyses are some of the topics covered in Part 1 of
this section of the handbook. Part 2 of Section 12 focuses on choosing heat
insulation for piping; orifice-meter selection; relative carrying capacity of
piping; water-meter sizing, liquid siphons, water hammer, compressed-air
and gas piping, design of steam transmission piping; desuperheater analysis;
steam accumulator selection and sizing; choosing plastic piping; estimating
costs of steam leaks; and line sizing for flashing steam condensate, plus many
other important energy-related fluid transfer calculations.
Interior climate control—heating, ventilation, and air conditioning—is
covered in Section 13 of the handbook. Since heating and air conditioning are
amongst the largest energy consumers in today’s commercial and residential
buildings, a large number of calculation procedures are presented in this
section. With the emphasis on LEED (Leadership in Energy and
™
Environmental Design) Green Building Rating System , there is intense
interest in energy conservation in every type of new building being
constructed today. Likewise, there is great interest in rehabbing existing
buildings so they, too, become LEED rated.
An interesting study of the outcome of the LEED program was recently
published. The study showed that LEED-rated buildings saved on energy
