a pipe is 40% blocked the water is coming into the region is moving at 8.5cm/s just before the blocked segment of pipe. What is the speed of the water as it goes through the partially blocked segment? By how many pascals does the pressure in the blocked segment decrease compared with the pressure in the normal pipe?

Start with the continuity equation and then apply the Bernoulli equation for the pressure change. Perhaps your alter ego "Steve" can help you with the continuity part.
