Question

Consider a 1,233 kg car cruising at constant speed of 71 km/h. Now the car starts to pass another car, by accelerating to 119 km/h in 7 s. Neglect air drag and friction and assume the road is level. By taking the entire car as the system and appying an energy balance, determine the additional power (kW) needed to achieve this acceleration to 1 decimal place. (note: 1 m/s = 3.6 km/h)

The car with 20000 N weight increases its speed uniformly from
18 km/h to 90 km/h in 40 s up the inclined rough road with 15
angle and the coefficient of kinetic friction between the car and
the ground is k = 0.5. Determine: ▪ the maximum power that must be
supplied by the car engine ( = 0.8), ▪ the average power supplied
by the engine. ▪ the initial kinetic energy T1 ▪ the final kinetic
energy T2 ▪...

A model car is tested in a large wind tunnel at an airspeed of
200 km/h. The model is 0.8m long and is a geometrically similar ¼
scale model of the full-size prototype car. If a drag force of
1.2kN is measured on the model in the wind tunnel, estimate the
power the full-size car would require to overcome the drag force
when travelling at a speed of 50km/h
How would you describe the flow? Are similarity conditions met?

In the autumn of 2007, Alaska Airlines executives adjourned at
the end of a long and stressful day in the
midst of a multi-day strategic planning session. Most headed
outside to relax, unwind and enjoy a bonfire
