1. PURPOSE

The purpose of this design analysis and calculation is to size a circulating pump for the service hot water system in the Shop Building 5006, in accordance with the Uniform Plumbing Code (Section 4.4.1) and U.S. Department of Energy Order 6430.1A-1540 (Section 4.4.2).

2. QUALITY ASSU-RANCE

This arialysis is non-Q because it is for a temporary item. A Determination of Importance Evaluation (Reference 5.1) of the Shop Building has determined that no quality assurance (QA) controls are applicable within the context of this analysis.

3. METHOD

The method used for the calculation is based on Reference 5.2. This consists of determining the total heat transfer from the service hot water system piping to the surrounding environment. The heat transfer is then used to define the total pumping capacity based on a given temperature change in the circulating hot water as it flows through the closed loop piping system. The total pumping capacity is used to select a pump model from manufacturer's literature. This established the head generation for that capacity and particular pump model. The total length of all hot water supply and return piping including fittings is then estimated from the plumbing drawings which defines the pipe friction losses that must fit within the available pump head. Several iterations may be required before a pump can hie se!ei;ted that satisfies the head-capacity requirements.

! length of pipe, L = 25 1 feet of 3/4 inch based on weighted average (Attachment I)

Substituting the appropriate design parameters in Equation (1) and solving for the heat loss through the insulated pipe, q = 1,119 BTUH.

The water flow rate in gaVmin to remove thk heat q is defined as:

Q = q/500 AT

where AT is the difference in temperature of the water leaving and returning to the water heater. The water flow limitation in piping systems is related to the velocity of flow and/or pressure drop which affects pumping costs. To minimize the erects of high velocities at AT in the hot water, return is limited to 1 degree which is reasonable for an insulated small diameter pipe line for service hot water. This results in a flow rate of 2.2 gallons per minute (gpm). From the UPC shown as Page 3 in Attachment I, the velocity of flow is 3 feedsecond and the friction loss is 4.5 psVlO0 feet pipe length if % inch diameter copper tubing is the minimum size used in the hot water return. However, as shown in Attachment I, the use of some '/2 inch tubing in the return results in a relatively high pressure drop. The minimum size tubing was increased to 3/4 inch which resulted in the selection of a

I circulating pump closely matching the required performance. I I I I

I The hot water circulating pump performance requirements are approximately 7 gpm at a system head I of 5 feet. A Grundfos closed system pump Model UPS 15-42F (SFD 2) was selected as the design I basis for the hot water return in the Shop Building. The pump shown in Attachment 11 is rated at I 1/25 horsepower at 230 V. I I The minimum pipe size is 3/4 inch type L copper water tubing. The pipe is designed for a minimum I of 1 inch insulation for added energy conservation while maintaining a hot water return temperature I of 109 degrees F. I I I I
