Part B: Water at 40 °C (p = 992.3; kg and v = 0.664 × 10-6 m²/s) flows through a pipe at point A (Figure Q2) with a diameter of 20 mm and a friction factor of f = 0.004. The water flows into a bath shower mixer unit at D, made from a tee junction. From here, water can exit along the tee branch through the spout via a gate valve (Figure Q2a) or along the main channel of the tee and through the showerhead (Figure Q2b). The water pressure at point A has been measured at 100 kPa. Loss coefficients for pipe fittings have been provided in Table 1. (a) If the water exits through the spout (Figure Q2a) via a fully opened gate valve at B, with a diameter of 12 mm, determine the flow rate out of the spout in L/s. The minor loss coefficient for the spout at B is Kspout = 0.6. Account for the minor loss in the elbow, the tee, and the gate valve. The gate valve at E is closed. (b) If the water emerges through the showerhead (Figure Q2b, point C) that consists of 100 identical holes, each with a diameter of 1.5 mm. Determine the flow rate out of the showerhead in L/s. The minor loss coefficient of the showerhead is Kshowerhead = 0.45. The gate valve at B is closed. Account for the minor loss in the three elbows, the fully opened gate valve at E, and the tee. (c) Discuss the differences in flow rate when water exits through the spout at point B versus exiting through the showerhead at point C.

Question

where M1=0.41m, M2=1.8m, M3=0.56m, please use bernoulis equation where necessary and The solutions should include, but not be limited to, the equations used to
solve the problems, the charts used to solve the problems, detailed working,
choice of variables, the control volume considered, justification and
discussion of results etc.
If determining the friction factor, the use of both Moody chart and empirical
equations should be used to verify the validity of the value.
