    8. Water flows through a horizontal pipe. The nozzle inlet has a cross sectional area (Ain) of 300mm2; the nozzle outlet has a cross sectional area (Aout) of 50mm2. The inlet velocity is 5 m/s and the inlet pressure is 300Kpa.
    Calculate Reynolds number based on nozzle diameter and water velocity both measured at inlet. State whether flow is laminar or turbulent.
    Calculate the volume flow rate (Q) and the outlet pressure (Pout). Assume that there are no energy losses.
    Hints:
    1) Use Bernoulli’s equation and eliminate relevant terms (the pipe is horizontal so there is no height difference i.e. and hence no potential energy change)
    2) For continuity . We can omit the density term from the Continuity equation since it will remain the same on both sides of the equation (30 marks)

    This is my Physics Fluids coursework question. I have a sort of an idea how to do it if explained to me properly. Unfortunately I have no idea on what to do thanks to my teachers very strong accent.

    We have been told to show the working out by the way.

    I feel like i'm locked in prison and the answer to this is the key to freedom.
