In a gas power plant, diesel fuel which can be represented by n-dodecane, cszh26, enters the steady-flow combustion chamber at 25°c, 1 atm, and is burned at a rate of 3.2 kg/s with 120% excess air which also enters the chamber at 25 c, 1 atm. the combustion products leave the combustion chamber at 1200 k. draw a schematic diagram of the combustion chamber, and identify various points on the diagram. for a complete combustion, determine: a) the air/fuel ratio b)-the mass flow rate of required air, c)-the rate of heat transfer from the combustion chamber.

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
