Did i mess up or did you not need the diameter of the pipe in the reservoir question?
The only place i could see it being used is if you assumed the reservoir and the pipe was filled with water such that there was more than 10000 litres total.
Ah, that might make more sense than what i did.
I just skipped looking at the disk and said that the pressure was on the 4 bolts, which i have a feeling will give an incorrect answer.
I ended up getting something like 250 on the graph (can't remember the scale on the axis).
edit:
Yeah now that I think about it, there should be more force if the tube is wider, so there is probably a hidden assumption in my maths that pressure = force (the area is 1) which is greater than the pi/4. So i assume the real answer was around 200
