Id say B.
Same principal as using gravity and a reduction in bore to make water cannon for gold mining. Was in a Clint film.. Pale Rider?
Morning, Spot on my view as well, same as if you ever want to fire a garden hose harder to clear debris, squeeze your finger over it.

There is no pressure at the exit of a pipe. Except for atmospheric pressure. All of the pressure energy is contained within the pipe. At the exit point, all of the energy becomes velocity energy. As discovered / explained by a very clever bloke called Bernoulli in the early 1700's.

Need to know the pressure in the pipe and diameter of pipe. And any hydraulic head. Then the velocity at the pipe exit can be worked out. Muck cleaning ability is the impact of the jet when it hits something (in this case a tratter door), which is the mass x velocity of the water jet.

Morning All. 
Late again, been gassing on the blower.
Damp and dismal here. How much electric is Milliband's Eco-energy delivering today? Only 20% that's what 18% wind, 2% solar.
Absolute lunacy on a grand scale and we are all going to pay for it for decades to come.
Other than that minor rant, have a thoroughly thrilling Thursday!
