Verification Case 7
PRODUCT: AFT Fathom
TITLE: FthVerify7.fth
REFERENCE: Ernest Brater, Horace Williams, James Lindell, C.Y. Wei, Handbook of Hydraulics, 7th Ed., 1996, McGraw-Hill, Page 6.31, Example 6.2
FLUID: Unspecified
ASSUMPTIONS: N/A
RESULTS:
Parameter | Handbook | AFT Fathom |
Head loss (meters) | 62.8 | 62.65 |
DISCUSSION:
The velocity and diameter are specified. For use in AFT Fathom, this is converted to a flow rate, obtaining 0.8482 cm3/sec. The unit weight is specified as 9580 N/m3. At 9.81 meters/sec2 gravitational acceleration, the density is thus 976.55 kg/m3.
The answers differ slightly because the handbook rounds off the Reynolds number to 3 digits.
No pressure boundary conditions are specified. In determining pressure drop, the boundary pressure plays no role. Therefore any value is suitable. The model assumes 1 MPa at the inlet.
