The air-handling units (AHUs) for Auric Enterprises, Inc., building, Problem 1-31, are required to handle 350,000 Btu/hr with a liquid-side head loss of 22 QZ,where Q is in cfs and the head loss is in ft-lbf/lbm, The cooling fluid, Monsanto TherminoI®, enters at 45°P and exits at 600 E Air enters the AHU at nop and leaves at 58°E The head loss (or pressure change) across the air side of the AHU is small, only a few inches of water.
(a) Determine the appropriate dimensions of the AHU core using one of the finned-tube surfaces appearing in Pig. 3-20.
Problem 1-31
(b) Given the physical layout of the building (Problem 1-31), do the dimensions determined in (a) result in a suitable arrangement?
For this problem use the following properties of Therminol. Complete properties are available at WWW.therminol.com.
