44 o t r d P P= (5.133) The tube clearance C t is obtained from Figure 5.21. C t = P t − d o (5.134) The number of tube N t can be predicted in fair approximation with the shell inside diameter D s. ShadeArea D N CTP s t π 2 4 = (5.135) where CTP is the tube count constant that accounts for the incomplete coverage of the shell diameter by the tubes, due to necessary clearance between the ...

A Design Example for a Rectangular Concrete Tank PCA ...

From page 2-18 of PCA-R, the maximum vertical moment coefficient is 149, looking at the Mx table. This moment occurs at the center-bottom of the wall. Similarly, the My table gives a maximum horizontal moment coefficient of 99, located at the top ends of the wall. For the moment calculations qu = (1.3)(1.7)(945 pcf) = 2,089 psf

Pipe Flow/Friction Factor Calculations using Excel ...

units typically used in the equations. Several example calculations are included and spreadsheet screenshots are presented and discussed to illustrate the ways that spreadsheets can be used for pressure pipe flow/friction factor calculations, including both laminar and turbulent flow and cases in which minor losses are included in the calculations.
