In a gas turbine, air (kinematic viscosity of 1x104-5 m 2/s) flows over a 2 cm long turbine blade at 100 m/s. how long should the blade be in my lab's wind tunnel (air, kinematic viscosity of 1.5x10a-5 ma2/s, velocity of 10 m/s), to match the reynolds number of the gas turbine? a)-2cm b)-30cm c)-0.3cm

30 cm

Explanation:

For  Reynold's number similarity between model and prototype we should  have

Given L(prototype)= 2cm

V(prototype) = 100m/s

V(model) = 10m/s

 Thus applying values in the above equation we get

Solving for Lmodel we get Lm = 30cm

Conceptual problem-solving skills

Explanation:

Conceptual problem-solving is a way of solving problems by applying what we know to what we do not know. For Clarisse who is an architect, the knowledge she has about visualization, and the concepts of the business world are not quite related.  

So to integrate her visualization solutions to business standards, she would have to compare the two spheres of knowledge to determine how to adapt one t the other.
