The aerodynamic drag of a prototype car is to be predicted at a speed of 25m/s at 2553C. Automopve engeneers buid a one-fith-scale Modul car ta linst in a wnd tunret under tha same enviranmental condsichs. The densty and viscosity of ar at 25C are 11kgm3 and 210kg/m5. respectively. It the dinension of the moded car a 1m. a) find the velocity of the model car b) If the drag force of the model car is 500N and the drag coefticiont is the same for both the modal and peototype. Find the power roquired to overcome the thing figece of the proposed prototype cas [4+610]
