Water flows through the pipe contraction shown below. Based on the information provided in the figure, determine the following: 0.15 m 0.35 m (i) The velocity of the water in the wider pipe (of diameter 0.15 m) and the overall flow rate of the fluid in the pipe as a function of D. (ii) The diameter D of the narrower pipe in order to achieve a 100% increase in the fluid velocity. (iii) Calculate the Reynolds number for both parts of the pipe. (iv) Following the contraction, a pump of 4 kW of power is used to elevate the fluid by 15 m. Calculate the head loss due to friction. Additional information: 3 Density of water: p= 1000 kg m Kinematic viscosity of water: v= 1.12 x 100 m s 1 Gravitational acceleration: g = 9.81 ms 2
