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.

answer; equivalent to a one(1) horsepower motor;

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
