Venturi Tube Question

  1. Jan 14, 2014 #1
    Hey guys. I can't figure out part 3bii) of this Venturi Tube Question.

    The answer I keep getting is 3.7907E-03 but it should be 3.95E-03. I'm definitely missing something but can't figure out what. I'm out by about 5%, could it just be down to rounding errors?

    Question and my working is shown in the attached pictures.


    Attempted Answer:

    Would really appreciate any help. Thanks!
