The airbus A-340 passenger plane has a maximum takeoff weight of about 260,000 kg, a length of 64 m, a wing span of 60 m, a maximum cruising speed of 945 km/h, a seating capacity of 271 passengers, maximum cruising altitude of 14,000 m, and a maximum range of 12,000 km. The air temperature at the cruising altitude is about -60 C (centigrade).Determine the Mach number of this plane for the stated limiting condition.
Entropy Generation in a Steam Turbine, Steam at a rate of 15lbm/s enters a turbine at 500 Psia, 800f and exits at 5 Psia. For a reversible, adiabatic process (iseentropic)
Consider a supersonic wind tunnel with test section Mach number of 2 and fixed geometry diffuser designed to operate with minimum stagnation pressure losses (smallest diffuser area).
The mean diameter of a conical friction clutch is 250mm with a width of the conical surface being 50mm. The clutch is lined with a material having a coefficient of friction of 0.25
A hydraulic shear applies 2000 lb force to a wedge. It is used to shear plate steel to rough size. The shear has a 1/4 inch thick cutting blade with a 45 degree slope. What is the ideal mechanical advantage of the wedge?
