Calculating every elbow individually is tedious. A common method for spreadsheets is the "Equivalent Length" method. You add a percentage to the straight pipe length to account for fittings. Calculating every elbow individually is tedious
Where:
h_f = 10.67 * Q^1.852 * L / (C^1.852 * d^4.87)
Even experienced engineers make these errors when calculating manually. The right spreadsheet includes to stop you.
