Question B1
a)
A horizontal pipe has a diameter of 7.0 cm on the left section and a diameter of 4.0 cm on
the right section.
Answer ALL questions in Section B
Water flows through the pipe from left to right and then out into the atmosphere with a
speed of 18.0 m.s-¹.
i) Calculate the pressure in the left section of the pipe.
ii) Calculate the volume of water that flows into the atmosphere in 30 minutes.
The density of water is 1000 kg m-³.
b) A block slides up a ramp that has an angle of 42° with respect to the horizontal. At the
bottom of the ramp (point A), the block has a speed of 10.0 m-s-¹.
The ramp is frictionless from point A to a point that is at a height of 2.5 m from the bot-
tom (point B). At point B, the block encounters a rough patch of length 1.0 m, where the
coefficient of kinetic friction is 0.37. The rough patch ends at point C. Figure 1 shows the
diagram of the block.
Determine whether or not the block reaches point C.
