    Was just looking for some help on how to calculate the pressure in a pipeline at a particular location. Consider the attached image for example. How would I calculate the pressure at the green arrow??

    Why are you trying to calculate it ? Might need a professional if you are building some.

    Also won't the pressure be the same the whole length of that pipe?

    The pressure will be equal to the pressure at the pipe inlet plus the 10m head pressure minus pipe frictional losses. However as the pipe enters the tank the pressure should dissipate. I suppose my question really is; can I work out the pressure at that point if I know the distance of that point from the tank inlet?

    Yes, based on the pipe size and material there are all sort of calculations and tables available e.g. http://www.efunda.com/formulae/fluids/calc_pipe_friction.cfm

    From the information you have the pressure is zero.
