The document calculates the difference in pressure between two points in a pipe with different diameters but constant flow rate, assuming no energy loss. It shows that with a diameter of 0.15m the pressure is 3.14m and with a diameter of 0.3m the pressure is 0.2m, giving a pressure difference of 2.94m. It then repeats the calculation with the diameters reversed, giving a pressure difference of -2.94m.

- 1. Assume no energie loss, calculate difference in pressure D=0,15 m D=0,30 m Q=140 l/s
- 7. Solution u2/2g=3,14 m u2/2g=0,20 m ∆p=3,14 – 0,20 = 2,94 m D=0,15 m D=0,30 m Q=140 l/s
- 8. Assume no energie loss, calculate difference in pressure D1=0.3m D2=0.15m Q=0.14 m3/s
- 10. Solution u2/2g=0,20 m u2/2g=3,14 m ∆p=0,20-3,14 = -2,94 m D1=0.3m D2=0.15m Q=0.14 m3/s
