PE 607: Oil & Gas Pipeline the pressure drop will be calculated according to CoxвЂџs and PoleвЂџs rule. The design The design pressure would be at 1 psig in horizontal pipe flow and the natural gas (NG) was used as

Elliptical duct: An elliptical duct made from aluminium has internal dimensions of 0.8 m at its widest point and 0.3 m at is highest point. The duct is 10.0 m long and carries a water flow rate of 400

Although the pressure drop ( p1 - p2 ) is 10 bar, we shall use for our calculation a pressure drop of only 0.6 x p1 [bara] = 6.6 bar because of the evaporation which occurs across the valve. Example Calculation of Pressure Loss using K-values This example demonstrates how to use the excess head method to calculate the head loss through simple pipe and fitting arrangement. The example uses water in system of standard weight carbon steel pipe.
