Gases produced during the combustion of a fuel-air mixture, enter a nozzle at 200kpa, 150°c and 20m/s and leave the nozzle at 100kpa and 100°c. The exit area of the nozzle is 0.03m². Assume that these gases behave like an ideal gas with Cp = 1.15 kJ/kg. K and Y = 1:3, and that the flow of gases through nozzle is steady and adiabatic. Determine i. the exit velocity ii. the mass flow rate.​

whoever your teacher is, deserves a raise for using pokemon as an example

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
