Automotive engineers plan to build a one-third scale model of a sports car and test it in a wind tunnel. The temperature of the wind tunnel is at 25°C. The drag force is measured with a drag balance and the moving belt is used to simulate the moving ground. If the sports car runs at 25°C, Wind tunnel test section L Fom Moving belt Drag balance Figure 4 Question 4 a) Propose the speed of the car that can be...
Problem 7-C: The aerodynamic drag of a new sports car is to be predicted at a speed of 70.0 mi/h at an air temperature of 25°C. Automotive engineers build a one-fourth scale model of the car to test in a wind tunnel. The temperature of the wind tunnel air is also 25°C. The drag force is measured with a drag balance, and the moving belt is used to simulate the moving ground (from the car's frame of reference) Determine how...
The aerodynamic drag of a new sports car is to be predicted at a speed of 75 km/h at an air temperature of 25°C. Automotive engineers build a one-fifth scale model of the car to test in a wind tunnel. It is winter and the wind tunnel is located in an unheated building. The temperature of the wind tunnel air is only 5°C. a) Determine how fast the engineers should run the wind tunnel in order to achieve similarity between...
The aerodynamic characteristics of a new car are to be predicted through a wind tunnel testing. Engineers build a one-fifth scale model of the car and placed it in the test section of the wind tunnel. The measured flow properties are given as Modet T+5°C, ?-1269kg/m 3 , ?-1.754 x 10-5 kg/m.s Prototype: T 25°C,p:1184 kg/m, ?#1.849 x 10-5 kg/mS, If the dimensional analysis results are outline as follows: V-50km/h Where, aerodynamic drag force, ? = density, V = speed,...
