QB1: Similarity Laws A water turbine is to be designed to produce 27 MW when running at 93.7 rev/min under a head of 16.5 m. A model turbine with an output of 37.5 kW is to be tested under dynamically similar conditions with a head of 4.9 m. Assume the water turbine efficiency is 88%. 1) Calculate the model speed and scale ratio. [12 Marks] 2) Estimate the volumetric flow rate through the model. [7 Marks] 3) It is estimated that the force on the thrust bearing of the full-scale machine will be 7.0 GN. For what thrust must the model bearing be designed? [6 Marks] TOTAL [25 Marks]
