In a steel pipeline of a hot water supply system with a diameter d = 0.0125 m and a length l = 100 m, water moves at a speed v = 0.5 m/s. Water temperature 50°C. The pipeline has two turns at an angle a = 90° and a plug valve. Determine pressure loss and compare with the results of calculations performed under the assumption of a quadratic resistance law.
