A diffuser in a pipe flow is basically a slow expansion of the pipe diameter, which slows down the fluid velocity and increases the pressure (the Bernoulli effect). Water at room temperature flows with a flowrate of 0.025 m/s through a horizontal diffuser in which the pipe diameter increases gradually from D1 = 6 to D2 = 11 cm. The irreversible head loss through the diffuser is estimated to be 0.45 m. The flow is turbulent, and the kinetic energy correction factors at both the inlet and outlet of the diffuser are assumed to be 1.05. (a) Calculate the pressure difference P2 - P1 in units kPa. (b)Calculate the change in energy grade line (AEGL) and the change in hydraulic grade line (AHGL). Does EGL go up or down? Does HGL go up or down? (c) Conceptual question - how would the EGL and HGL lines look if we had no losses in our system? VI V2 D2 P P2

From a PPRC (shiny surface) pipe with an inner diameter of 20.5 mm and a length of 70 cm, water at 20 ° C flows at a flow rate of 1500 L / h and a pressure difference of 52 mbar occurs. Based on these data, find the speed of the water, the Re number, the friction factor, the f value and the pressure difference (in mbar) and show the f value you found from the Moody diagram.
