Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

1. A piston-prop aircraft has a wing loading of 1600 N/m², wing area of 25 m² and its drag polar is given by Cp 1.5. The reciprocating engine develops 750 kW at sea level, and the propulsive efficiency of the engine-propeller combination is 0.85. Draw the power-available and power-required curves at sea level. Determine the maximum and minimum speeds for level flight at sea level. What is the minimum power required for level flight at sea level? Determine the corresponding velocity and lift coefficient. 0.025 + 0.05C. The maximum lift coefficient is

3. A truck has a drag coefficient based on frontal area of CD = 0.86. The truck has a mass of 12,750 kg and a frontal area of 10.5 m2. If the truck is traveling at constant speed on a level road, the forces retarding its forward progress are the drag and the rolling friction. The force due to rolling friction can be written as Fit Wfr(1+ V V₁ where V is the truck speed in m/s, Vo = 30 m/s and fr (the coefficient of rolling resistance) is approximately 0.008 for a truck on concrete or asphalt. Plot the total power the engine must supply as a function of truck speed, V. Comment on the relative importance of drag and rolling friction in the fuel consumption of the truck.
A non spinning ball having a mass of 3.5 oz is thrown vertically upward with a velocity of 100 mph and has zero velocity at a height of 210 ft above the release point.
