A pure jet engine propels an aircraft at 250 m/s through air at 45 kPa and -13 °C. The inlet diameter of this engine is 1.6 m, the compressor pressure ratio is 13, and the temperature at the turbine inlet is 557 °C. Determine the velocity at the exit of this engine's nozzle and the thrust produced. Assume ideal operation for all components and constant specific heats at room temperature.
a curved nozzle assembly that discharges water to the atmosphere is shown. The nozzle mass is 4.5 kg and its internal volume is 0.002 m^3. The fluid is water. determine the reaction force exerted by the nozzle on the coupling to the inlet pipe.
The effect on temperature and density of air under adiabatic compression, Air is going through a compressor
wind turbines are becoming more and more common as a method of energy production wind turbines by their very nature are
A bullet is fired vertically at a latitude of 50 degrees N with a muzzle speed of 1000m/s. Neglecting air friction, determine the landing point of the bullet.
A 0.7-lb block rests on top of a 0.5-lb block supported by but not attached to a spring of constant 9 lb/ft. The upper block is suddenly removed. Determine (a) the Maximum velocity reached by the 0.5-lb block, (b) the maximum height reached by the..
