a. Calculate the scale of the model if viscosity and weight are both needed to ensure similarity.
b. What should the model scale be if oil with viscosity 92.9x 10 ^ -6 m² / sec is used in the test of the model and if the prototype fluid has viscocity 743.2 x 10 ^ -6 m² / sec?
c. What will be the speed and flow ratio for the 1: 4 scale prototype model fluids?
