Heat transfer. Could anyone explain the solution?

AI Thread Summary
In the discussion on heat transfer, a participant seeks clarification on why the heat transfer coefficients h1 and h2 are equal in a steady-state scenario. The problem involves equal heat flow rates from points B to C and C to A, which is essential for maintaining constant temperature at point C. It is emphasized that only conduction is considered, with no radiated losses, leading to the conclusion that heat flow rates must be equal. The participant ultimately understands that the equality of heat flows justifies h1 equaling h2. This highlights the importance of steady-state conditions in heat transfer analysis.

The Attempt at a Solution


This is a solved question. The answer is given above.
I can't understand why h1=h2.

Assume that ##T_C## is between ##T_A## and ##T_B## and that there are equal heat flow rates ##B \rightarrow C## and ##C \rightarrow A## (because we want to calculate steady-state temperatures, and without the equality of the rates the ##T_C## would be changing).

H = heat flow. Heat H1 flows down B->C. The problem says to assume only conduction (eg through the rods) no radiated losses so where else can that heat flow go if not down C->A ? Therefore H1=H2.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
