Question

To conserve water and energy, a “flow reducer” is installed in the shower head as shown in Fig. P8.57. If the pressure at point (1) remains constant and all losses except for that in the flow reducer are neglected, determine the value of the loss coefficient (based on the velocity in the pipe) of the flow reducer if its presence is to reduce the flowrate by a factor of 2. Neglect gravity

We have to consider two dierent cases, i.e., without the ow reducer and with ow
reducer.
1. Without the ow reducer, we can write the equation,

and, p2 = 0, z1 = z2, and,
