Figure A2 shows a hydraulic system that delivers water to a hydro-power turbine (not shown) that is driven by the high-speed jet of water that comes out of the nozzle at C. The water that flows through the system originates from a lake that has its surface marked O. It is assumed that the lake is large enough for its surface-level to remain unchanged throughout the delivery of water. The pipe section from A to B has a diameter 40 cm while the exit diameter of the nozzle is 5 cm. Assume ideal steady flow. Take the density of water to be 1000 kg/m³ and the acceleration due to gravity to be 10 m/s². jet of flange bolts water 35 m 45 m 40 cm 5 cm Figure A2 (0) Using the Bernoulli equation, determine the speed of the water jet at Point C. (ii) Determine the mass flow rate through the system. (iii) Determine the flow speed in the pipe section between Points A and B. (iv) Determine the gauge pressure in the pipe at Point B. (v) Explain why the pressure at B is higher than atmospheric pressure. (vi) Determine the force experienced by the nozzle (that the flange bolts must resist).
