The front and side views of a centrifugal impeller are shown in the figure below. All symbols have their usual meanings. The outer radius of the impeller is r2 = 0.4 m and the blade height at the impeller outlet b2₂ = 0.03 m. The volume flow rate of water (density = 1000 kg/m³) through the impeller is 0.2 m³/s. The outlet blade angle 8₂ = 50 degrees and the impeller rotational speed w=1600 rpm. Assume negligible losses, and the design conditions of whirl-free and shock-free entry. The impeller torque is B₂F N-m. Front View 12 b2 |+| Side View

The system in Fig 2 pumps water from a lower reservoir to a higher reservoir. The pipe diameter is 0.235 m and the pipe lengths are L1= 5 m, L2= 4.5 m, L3= 1.5 m, and L4= 0.6 m. The impeller of the centrifugal pump has a diameter of 0.55 m and operates at 850 rpm. The uniform blade height is 51 mm. The water enters the pump parallel to the pump shaft with a flow rate of 0.16 m3/s. Take viscosity as 0.00112 N s/m2. Fig Q2: Piping system to pump water between two tanks. Work to 4 significant digits. Enter all values using base units or their combinations, i.e. m, m/s, Pa, N. Do not use multiples as e.g. mm, kPa. You can use values with exponents, such as 0.12e3. a) What would be the shaft power required to turn the impeller if the exit blade angle is 31 degrees. b)
