A model boat, 1/100 size of its prototype has 0.12 N of resistance when simulating a speed of 5 m/s of the prototype. Water is the fluid in both cases. What is the corresponding resistance in the prototype?
[The frictional forces can be neglected]

Detailed Solution for Test: Dimensional & Model Analysis - 2 - Question 2

The resistance offered at the free surface is the significant force and as such Froude model law is appropriate

Oil of density 917 kg/m3 and dynamic viscosity 0.29 Pa.s flows in a pipe of diameter 15 cm at a velocity of 2 m/s. What would be the velocity of flow of water in a 1 cm diameter pipe to make the two flows dynamically similar? The density and viscosity of water can be taken as 998 kg/m3 and 1.31 x 10-3 Pa.s respectivley.

Detailed Solution for Test: Dimensional & Model Analysis - 2 - Question 3

In this case, Reynolds similarity law is applicable 

Referring to oil with a subscript p and water with a suffix m

∴

A 1 :5 scale model of a passenger car is tested in wind tunnel. The prototype velocity is 50 km/h. if the model drag is 200 N, what is the power required to overcome the drag in the prototype? The air in the model and prototype can be assumed to have the same properties.
Detailed Solution for Test: Dimensional & Model Analysis - 2 - Question 4

Reynolds similarity law is applicable 


∵ air is having same properties,
(Fm/Fp) - 1
∴
