Problems i there is power plant for a 100-m height and 4-m diameter stack whose exit gas has a velocity of 30 m/s. the wind velocity is 5 m/s with the stability class of c. the pressure is 1 atm, and the stack and surrounding temperatures are 100°c and 20°c (373k and 293k), respectively. estimate plume rise using briggs equation. when gravity acceleration g is 9.8 m/s2 problems ii in problem i, a power plant emits 200 g/s of so2. estimate the ground-level concentration of so2 from this source at a distance 2km directly downwind when the stability class is c problems iii for the same situation of problem ii, calculate ground- level concentration 250m to the side of the plume centerline. m problems iv 최까학지2. 지점 what is maximum ground level concentration and where is it located downstream in problem ii ?

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

i think the answer would be reserve.

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

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
