Question
A vertical pipe is shown in figure 1 below. The pipe tapers from 50 mm in
diameter to 25 mm in diameter. If 2 liters of water per minute flow upwards
through the pipe the pressure difference across the pipe is 35 kPa. Calculate
the flow downwards through the pipe if the pressure across the pipe is to be
zero. The losses across the pipe are given by h, = K-vi), where v, and v,
are the velocities in the 50 mm and 25 mm sections respectively.
