Estimate the maximum range and the maximum endurance of a propeller-driven airplane with the following characteristics: empty weight 4000 lb, fuel weight 400 lb, specific fuel consumption 0.4 lb of fuel per horsepower per hour, propeller efficiency 0.8, zero-lift drag coefficient 0.03, wing area 200 ft2 , aspect ratio 7, and Oswald efficiency factor 0.85. Assume the standard sea-level conditions. Note: you may want to use some results given in section 6.14 of the textbook.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.
