Question

Streamlines and conical funnel.

unsure how to start this question, part a) is confusing.

The streamlines in the conical nozzle shown in Figure 1 are essentially radial lines emanating from point A and the fluid velocity is given approximately by V C/r2, where C is a constant. The fluid velocity is 2 m/s along the centreline at the beginning of the nozzle (x 0) Q1. a) Write an equation that describes the relationship between r and x on the jet centreline [2 marks] 14 marks] [5 marks] [4 marks] b) c) d) Find the value of the constant C. Determine the acceleration along the nozzle centreline as a function of x. what is the value of the acceleration at x 0 m and x = 0.3 m? 0.6m 0.3 m 0
