Air at 15?C and 0.01 atmospheres pressure flows over a thin flat strip of metal, 0.1 m

Question:

Air at 15?C and 0.01 atmospheres pressure flows over a thin flat strip of metal, 0.1 m long in the direction of flow, at a velocity of 250 m/s. Determine (a) the surface temperature of the plate at equilibrium and (b) the rate of heat removal required per meter width if the surface temperature is to be maintained at 30?C.GIVENHigh speed air flow over a thin flat strip of metalAir temperature (T??) = 15oC = 288 KAir pressure (P) = 0.01 atm = 1013 N/m2Metal strip length (L) = 0.1mAir velocity (U??) = 250 m/sASSUMPTIONSAir flows over one side of the strip onlyAir behaves as an idealgas

For this experiment we need-One glass bottle (opening slightly smaller than an egg)-A matchbox-One peeled boiled eggIn this demonstration, the lit matchsticks heat the air inside the bottle. When air is heated it expands and some of it escapes out of the bottle. When the matches go out, the air inside the bottle cools and contracts thus creating a lower air pressure area inside the bottle than outside. Normally, the high-pressure air outside the bottle would come rushing in to equalize the low-pressure air in the bottle. The problem is that the egg is in the way. The air molecules on the outside of the bottle push the egg into the bottle.•Procedure• Place a glass bottle on the table.• Boil a normal-sized egg and• Place the boiled egg on the face or neck of the bottle.• We can see the egg cannot be pushed into the bottle because of air inside the bottle.• Now light the matches at the same time and drop them into the bottle.• Once the matchsticks have been dropped into the bottle Quickly Place the egg over the neck of the bottle.• You can see the egg is sucked into the bottle.This represents the air pressure and characteristics of air.
