Question 1 a) Kindly design an open channel section for an estate

Question 1 a) Kindly design an open channel section for an estate developer with the problem of disposal of kitchen liquid waste which is a challenge affecting his business. He wants the flow depth of the channel section to have a constant velocity for sewer discharge of about 1100 kg/m. CR(8) b) In your own opinion, is friction factor inversely proportional to the Reynold's number in case of laminar flow in circle pipes? [qualitative response EV(5) c) The small turbine in shown below extracts 400 W of power from the water flow. Both pipes are wrought iron. Compute the flow rate Q m/h. Why are there two solutions? Which is better and why? V d] Water 20% C 20 m (1) Turbine 10m D = 6 cm (2) 30 m D = 4 cm EV (7) An engineer claims that flow of SAE 30W oil, at 20C, through a 5-cm-diameter smooth pipe at 1 million N/h, is laminar. Do you agree? A million newton's is a lot, so this sounds like an awfully high flow rate. CR (5)
