In this scenario a battery is used to supply chemical potential energy. the potential energy is transformed and produces kinetic energy. the battery causes a fan to spin and that kinetic energy can also be described as mechanical energy. check out the values for each: 100 j potential energy results in 75 j of kinetic energy. what conclusion can be drawn from the energy transformation diagram?

2kg of refrigerant 134a undergoes a polytropic process in a piston-cylinder assembly from an initial state of saturated vapor at 2 bar to a final state of 12 bar, 80 degree c. a)determine the work for the process in kj. b)sketch the process on a p-v diagram.

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.
