Q1. In the design of a shower head, a "flow reducer" is installed to conserve water and energy as shown in Figure 1. After installation, the flow rate, Q, is reduced by a factor of 2. Assume the following: The pressure at (1) remains constant before and after installation of the flow reducer All losses, except for those in the flow reducer, can be neglected. The effects of gravity can be neglected. a) Find the pressure at (1) in terms of the flow rate, Q [4 marks] b) Determine the value of the loss coefficient, KL, of the flow reducer.
