Un africano que se encuentra a 20 m de un león hambriento arranca con una rapidez constante de 36 km/hr, alejándose en línea recta del león, que está inicialmente detenido. el león tarda 2 segundos en reaccionar cuando empieza a perseguir al africano con una aceleración de 4 m/s2, siempre en línea recta hacia el africano, que huye hacia un árbol que se encuentra más adelante en la misma recta. a) hacer un esquema ilustra-tivo de la situación. b) ¿cuál debe ser la máxima distancia a la que debe estar el árbol para que el africano pueda subirse justo antes que el león lo alcance? c) calcular la rapidez con la que el león llega al árbol. r: b) 116m, c) 30.4 m/s.

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
