The impeller of a centrifugal pump has an internal
diameter of 200 mm and external diameter 400 mm. The
widths of the impeller at entry and exit are 20 mm and 10
mm respectively. The discharge of water through the
impeller is 20L/s. The impeller rotates at 1440 rpm and
the blade angle at the outlet is 30 degrees. Determine the
pressure head rise in the impeller neglecting friction
losses.
A water jet with a flow rate of 2.83 m3 / s is traveling at 6 m / s in the positive x direction. The cost of the current striking a stationary splitter is correct about a 45 aç angle, other company are deflected downwards by the same angle and the final velocities of the two streams are 6 m / s. By neglecting the gravity, the separator is in place against the force applied by the water. calculate the x- and z- power of what is required to hold it. For water ? = 1.184 kg / m3
