What about the upper and lower boundaries? Bc should be x=0 t=to X=b/2 t=to Y=0 dt/dy =0 Y=b t= to(x)

Shouldn't we found T(x,y) and for upper and lower parts should I write as afuction of x To(x) and then define new temperature variable Q=T-To to eliminate nonhomog on the left side

Homework Statement Homework Equations ıt is nonhomog type ,2D heat conduction problem The Attempt at a Solution I don't understant To parts so I couldn't attemp a solution.

I am always confused with cylindrical coordinates. I know how to solve this but I couldn't formulate the problem as you sad I added z term.

Homework Statement A very long cylinder has temperature T1 impressed on half of its peripheral surface and temperature T2 impressed on the other half. Find T(r, θ).Homework Equations governing eq 1/r ∂/∂r(r∂/∂r)+∂2T/∂z2 The Attempt at a Solution I am right at r=0 ;T=T1 at r=r' T=T2 to make BC...

1 kmol of oxygen at 25C and 100kPa and 1 kmol of nitrogenat 25C and 100kPa from atmosphere

Homework Statement Atmospheric air at 300K and 100kPa is to be delivered to a line at 600K, 200kPa. Two possible schemes for doing this are suggested. The first scheme involves reversible adiabatic compression and then internally reversible isobaric heating. .The second scheme involves...

1. assume air is an iseal gas at 25C and 100kPa. the mole fractions of components are nitrogen_0.7567 oxygen=0.2035 water vapor=0.0303 carbon dioxide=0.0003 Calc. min work to seperate a-1kmol O2 at 25C 100kPa b-1kmol N2 at 25C 100kPa from atmosphere Homework Equations...
