Homework Statement
Water flows in a pipe with speed 1.5 m/s at point 1.
The diameter of the pipe at point 1 is 4cm and the diameter at point 2 is 3cm.
density of water: 998.2071 kg/m^3
What's the speed of the water at point 2?
Homework Equations
I think you need to use this. I just have no idea how to find pressures p_1 and p_2 which seems to be needed to get the solution v2 out of this:
p_1+0.5ρ(v_1)^2 = p_2+0.5ρ(v_2)^2
The Attempt at a Solution
Trying to find the pressure difference p_2 - p_1
At this point I realize it's impossible because you need to use the equation above and it's also needed to solve v_2. No idea what else I could do.
