The Automatic Pressure Drop calculator is an Excel spreadsheet that has been set up to determine the pressure drop characteristics of Piping Packages and Hose Kits based on component pressure loss data. The steps to using the calculator are defined below: 1) 2)
You must know the content of the kit you would like to determine the pressure drop for. Fill in the information in the header of the worksheet "Input Sheet". a) Choose connection size in dropdown box of cell E3 (This number is only used if no flow value for a Mesurflo is entered in cell E6). b) Choose schedule number of pipe used for connection size, generally schedule 40, from dropdown box in cell E4 (Once again this value is only used if there is no flow rate entered in cell E6). c) If the kit will contain a Mesurflo valve choose the Mesurflo modelfrom dropdown box in cell E5. If no Mesurflo is to be present choose "None". d) Choose the flow rate desired for the Mesurflo from the dropdpwn box in cell E6. All available flow rates for that model Mesurflo are listed. If no Mesurflo is to be used you reselect the blank entry for the drop down box.
e) Choose Ethylene for Ethylene-Glycol / Water mixtures, Propylene for Propylene-Glycol / Water mixtures or Water / no from the dropdown box in cell in cell E7. If the fluid is to be 100% water use any entry with 0% concentration. The density calculated for the mixture and temperature entered will show up in cell F7. f) Enter the percent of Glycol in the fluid mixture in cell E8. Concentrations up to 90% may be used. The calculator will adjust the operational volumetric flow of the Mesurflo valve based on the Glycol concentration per Technical Bulletin 2005-02. f) Enter the Temperature of the fluid in degrees Fahrenheit in cell E9. This is once again used to determine the density and hence control point of the Mesurflo valve. Valid ranges of temperature are 35 to 212 °F. g) Enter the Cv of the ATC, if present, in cell E10. This field can also be used to add in components that are not available as part of the already defined components. If there is no ATC present enter a zero in this field. h) If a heat exchanger is not present enter zero in cells E11 and E12. If a heat exchanger is present enter the values for Z and X from curve fits of the heat exchanger data. See Technical bulletin 2006-02 for information on how to use these inputs. i) If the pressure drop at a specific flow is desired enter the flow (in gpm) in cell E13. The pressure at that flow for the kit defined below will appear if the data is valid. 3) Define the components of the kit by placing the quantity of the components used in the dropdown box next to the model and size value. The selection of sizes will correspond to the respective model chosen. Extra rows are given to enter different strainer models or enter different sizes of the same model. Note: It is not advisable to enter the identical component model and size in two successive colums. For example, do not select Strainer model Wye-tpe, size say 1/2"-1/2", quatity 1 in first column and select the same model type and size in second column with quatity 1 to calculate the pressure drop for two same strainer type with same size. In that case, the pressure drop will only be calculated based on the quantity mentioned in first column. Instead, if the model type and corresponding size are same, always put the toal number of quantities in the same column. 4) For example in a 243143.00YMH432C64XX piping package used with 100% Water at 60 °F the following entries would be made: a) Header i) Connection Size 0.5 ii) Schedule 40 iii) Mesurflo GPM 3.00 iv) Type of Glycol E v) Percent Glycol 20 vi) Temperature 35 vii) Cv of ATC 2.9 viii) Z and X value used to simulate pressure drop of a heat exchanger are both zero b ) Components would be as follows
(i) Under strainers heading, select the strainer type from the dropdown box, the corresponding sizes will be shown in size selection. Then select the required size from available sizes in the dropdown box. Enter the total quantity in respective column. In case of different strainer types and sizes, repeat the same process in successive rows and keep adding the quantities. (ii) Selection of hoses is same as strainers. Select the hose length first, select the hose diamter and enter the number of quantities. Under hoses there would be a quantity of 2 (supply and return) next to 24” Long by ¾” Diameter hose, all other strainers would have a zero for quantity.
5)
(iii) Repeat the steps for all the required components. All of the items are set to none by default. (iv) Under Mesurflo there would be a 1 next to 2514, all other entries would be zero. (v) All of the items under Isolation ball Valve would have a quantity of zero. c) The input sheet for this example is provided below and the graph resulting from these entries is provided below that. d) There is an additional feature addes to this updated pressure drop calculator. Based on the Mesurflo Model selected, the image of the respective model will be displayed as shown below. The cells with red fonts are intended for feedback to the user. They are for the following purposes: a) On connection size and schedule the spreadsheet will feedback the nearest size it uses to calculate a maximum flow rate. This value is not used if a value for flow control is provided in cell E6. b) The value in cell F8 is the percentage of Glycol used in the density calculation. This should be the same as the value in cell E8. c) The temperature used in the calculation of fluid density is provided in cell F9. This should be the same as that typed in to cell E9 unless the value in E9 is out of range. The pressure drop will be determined for out of range conditions, however, the results can not be guaranteed.
